This study investigates the electrochemical performance and microstructural characteristics of methanol–water electrolyzers according to the ionomer-to-carbon (I/C) ratio range of 0.5–2.0 in electrode catalyst layers. The lowest voltage at the same current density is observed at an I/C ratio of 1.5 at the anode. When the I/C ratio was 2.0, the voltage was observed to be approximately 25% higher than that at an I/C ratio of 1.5. A microstructural analysis shows a decrease of the specific surface area due to catalyst agglomeration at I/C ratios higher than 1.5. The results of the BET analysis showed a decrease in the surface area with an increase in the I/C ratio. Furthermore, when the I/C ratio exceeds 1.5, separated layers of excessive amounts of ionomer are observed, possibly blocking the electron conduction pathways in the electrode catalyst layer. The energy conversion efficiency of the developed methanol–water electrolyzer was assessed in an current density range of 0.08–0.80 A cm−2, demonstrating values between 81.4% and 92.4%.","PeriodicalId":14238,"journal":{"name":"International Journal of Precision Engineering and Manufacturing-Green Technology","volume":"25 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140197077","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, practical implementation of this technology remains limited, requiring substantial effort and costs. This study addresses the challenges specific to nuclear power plants, characterized by hazardous environments and physically demanding tasks such as nozzle dam replacement in confined workspaces. We propose a digital twin and deep-reinforcement-learning-driven robotic automation system with an autonomous mobile manipulator. The study follows a four-step process. First, we establish a simplified testbed for a nozzle dam replacement task and implement a high-fidelity digital twin model of the real-world testbed. Second, we employ a hybrid visual perception system that combines deep object pose estimation and an iterative closest point algorithm to enhance the accuracy of the six-dimensional pose estimation. Third, we use a deep-reinforcement-learning method, particularly the proximal policy optimization algorithm with inverse reachability map, and a centroidal waypoint strategy, to improve the controllability of an autonomous mobile manipulator. Finally, we conduct pre-performed simulations of the nozzle dam replacement in the digital twin and evaluate the system on a robot in the real-world testbed. The nozzle dam replacement with precise object pose estimation, navigation, target object grasping, and collision-free motion generation was successful. The robotic automation system achieved a (92.0%) success rate in the digital twin. Our proposed method can improve the efficiency and reliability of robotic automation systems for extreme workspaces and other perilous environments.","PeriodicalId":14238,"journal":{"name":"International Journal of Precision Engineering and Manufacturing-Green Technology","volume":"26 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-03-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140151684","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, the thin film electrolyte can effectively offset the drop in ion conductivity at a low operating temperature due to a reduced ion path. In this study, the performance difference of solid oxide fuel cells according to the thickness of these thin film electrolytes was compared. Thin film solid oxide fuel cells were fabricated with YSZ electrolytes of 3.3 μm, 4.0 μm, and 4.7 μm thickness using different sputtering deposition times. First, the thickness of the electrolyte affected the gas tightness. The OCV of the cell using the 3.3 μm, 4.0 μm, and 4.7 μm thick electrolyte showed 1.01 V, 1.03 V and 1.05 V respectively. As the sputter deposition time increased, the surface grain size of the YSZ electrolyte also increased, affecting both the electrolyte's ohmic and the electrode's polarization resistance. Therefore, the difference in the thickness of the electrolyte showed a dramatic difference in performance. The cells with 3.3 μm, 4.0 μm, and 4.7 μm thick electrolytes showed performances of 193 mW/cm2, 99 mW/cm2, and 57 mW/cm2, respectively at 500 °C.","PeriodicalId":14238,"journal":{"name":"International Journal of Precision Engineering and Manufacturing-Green Technology","volume":"30 3 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140151370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, a flutter-driven piezoelectric nanogenerator (FD-PENG) using electrospun PVDF nanofiber was fabricated to create a wind-energy harvesting device. The FD-PENG was composed of a PVDF nanofiber mat (active layer) and Al foil (electrodes), with these components encapsulated by polyethylene terephthalate (PET) film using an ordinary coating machine. The short-circuit current generated from the FD-PENG during a bending test was significantly enhanced by optimizing the electrospinning process and with the proper alignment of the PVDF nanofibers. The dynamic behavior of the FD-PENG with respect to various wind speeds was systematically analyzed by categorizing its motion into four distinct modes. The flapping mode, in which the FD-PENG displays the largest amplitude of oscillation, was induced when wind speed was in the range of (3-4~mathrm{ m}/{text{s}}). The FD-PENG generated open-circuit voltage of approximately 10 V at a wind speed of (4~mathrm{ m}/{text{s}}) and exhibited excellent durability over 10,000 cycles. Using a single FD-PENG, maximum power approaching 14.66 μW was achieved under an external load of 1.1 MΩ. Furthermore, the wind speed inducing the flapping mode was modulated by the shape of the FD-PENG. The results here show that the wind energy harvester can be applied at a wide range of wind speeds by modifying the shape of the FD-PENG.","PeriodicalId":14238,"journal":{"name":"International Journal of Precision Engineering and Manufacturing-Green Technology","volume":"67 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140075303","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Today, as a blade size is getting bigger, not only it is hard to find the test facility incorporating blade over 100 m, but also a blade test time and test cost required for certification according to IEC 6140023 are also increased, which could cause the delay of product entrance to wind energy market. The proposed biaxial segment test method mainly aims at improving the efficiency of the fatigue test because fatigue test takes up more than 70% of total test time and 60% of total test time approximately and is also intended to utilize existing test facilities through the segmentation of a large blade. For the feasibility assessment of the novel methodology, the virtual test model of the fatigue test configuration was constructed including virtual mass element, spring element, damping element, blade beam element, and kinematic lever-arm mechanism. Through the optimization process, it was found out that the proposed test methodology has a significant time saving up to 36% compared to conventional blade test method for 90 m blade test, which is even 17% further saving compared to uniaxial segment test. Also, the proposed methodology could save cost by 17% compared to traditional method. Among categories constituting the total cost calculated from 90 m blade case, electricity cost category related to hydraulic pumps necessary to maintain high forces was increased by 7% while labor and material costs reduced by 3% and 3% respectively compared to traditional test approach. The current study also showed that the biaxial segment test method is even more effective for a supersized wind blade. For the 115 m blade, the cost reduction rate was even higher by 5% than one of 90 m blade in addition to the utilization of the existing test facility.","PeriodicalId":14238,"journal":{"name":"International Journal of Precision Engineering and Manufacturing-Green Technology","volume":"20 1","pages":""},"PeriodicalIF":4.2,"publicationDate":"2024-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140075186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study sought to determine the optimal Pt loading for flexible PEMFCs, to reduce waste of catalyst and find a cost-effective solution. The optimal catalyst loading for flexible fuel cells varies depending on the operating environment and conditions. In environments requiring the generation of high power regardless of operating voltage, the optimal Pt loading is 0.1 mgPt cm−2. In contrast, in environments where higher voltage is required with a minimum stacking, the optimal Pt loading is between 0.3 and 0.4 mgPt cm−2.
