The burner construction and the calculation of maximum burner power are showed in detail. Meanwhile, its static characteristics are researched through the influence of excess air ratio (ER), air velocity, inlet air temperature and fuel utilization rate (Uf); its transient characteristics are researched through the processes of burner start-up, burner operating state switch and stack start-up. Results suggest that the best ER value gets larger with the increased burner power. The air velocity is better controlled within 3 m·s-1 to prevent the influence of lifted flame. High inlet air temperature can extend lean combustion range and reduce incomplete combustion products, but large ER mutation should still be avoided. In case of anode off gas combusting with cathode off gas, there are nearly zero emissions. Meanwhile, the flue gas temperature decreases to about 760 °C because of enlarged heat loss, but it is minimally influenced by Uf. Under static condition, the optimal point with both controlled temperature and lowest emissions can be obtained in wide range, and the after-burner can well adapt to various operating states of the stack. Under transient condition, the after-burner has good response performance with much shorter time in burner start-up and burner operating state switch than conventional porous media ones. It can start up the stack in 1715 seconds.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2022-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42773766","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hydroxyl groups are consumed due to the interaction with silica oxides and depleted the crystalline phase of the composites. The tensile strength and modulus of the composite membranes were reduced. The addition of RM improves the thermal stability of the composite membrane and shifts the degradation process to a higher temperature. The RM nanoparticles depleted the hooping sites for methanol transport in the composite membrane and the permeability value reported in the modified membrane was one order lower than the Nafion (N117) membrane. The proton conductivity of the composite membranes are obtained by fitting the EIS data in an equivalent circuit model. The composite membrane provides higher proton conductivity at reduced relative humidity conditions and the proton transport was governed by Grotthus mechanism. The modified membrane provides the maximum power density of 44mW/cm2 at a current density of 140mA/cm2. The durability test was conducted at a current density of 0.15 Acm2 and 70°C for 144h to evaluate fuel cell performance and voltage decay. The durability study confirms that the modified membrane provides higher cell stability with marginal drop in cell voltage (1.76%).

The method firstly preprocesses the voltage signal of lithium battery by optimal variable mode decomposition to obtain the high and low frequency components of the signal, and reconstructs the high and low frequency components. Then the dimensionless feature parameters are extracted according to the reconstructed signal and feature reduction of the dimensionless feature parameters is carried out by a local linear embedding algorithm.

If the charging and discharging strategy does not adjusted with the aging state, it is easy to cause battery abuse and accelerate the decline. In order to avoid this situation, the aging model with consideration of the battery degradation is coupled into the pseudo-two-dimensional (P2D) model. An aging effect-aware finite element model that can describe battery physical information accurately is presented in this paper. The model parameters are divided into four parts: structure parameters, thermodynamic parameters, kinetic parameters and aging parameters. The identification experiments are designed based on the characteristics of these types of parameters. The decoupling and parameter identification methods of kinetic parameters according to the response characteristics of each parameter under specific excitation, and state of charge (SOC) partitioned range identification technology of aging parameters are proposed and verified. Finally, the aging effect-aware model and the identification parameters are verified under constant current (CC) and different dynamic conditions with different charge rate (C-rate). And the ability of the proposed model to track the aging trajectory in the whole life cycle is verified under various cycle conditions. The proposed model can be applied to aging mechanism analysis and health management from point of inner properties of the batteries.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2022-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"63503807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drying process of a dispersion directly influences the structure and properties of the resulting dried film. Thus, it is important to investigate the underlying physics of dispersion drying and the effects of different drying parameters. This article reviews modeling studies of coating drying processes, along with corresponding experimental observations. We have divided drying processes into two conceptual stages. In the first drying stage, liquid evaporation, particle sedimentation and Brownian motion compete and affect the particle distribution during drying and thus in the final film structure. We have included a comprehensive discussion of the influences of drying parameters, such as evaporation rate, particle sizes and temperature, on the above competition and the resulting film structure. A drying regime map describing where different drying phenomena dominate was formulated based on the literature. We also extended our discussion to the practical applications of battery slurry drying an essential step in conventional battery electrode manufacturing. In the second drying stage, the physics of porous drying and crack formation are reviewed. This review aims to provide a comprehensive understanding of dispersion drying mechanisms and to provide guidance in the design of film products with favorable structures and properties for targeted practical applications.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2022-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47306733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Partial oxidation reforming(POX) can be used to simplify SOFC system structure, but its lower hydrogen production rate deteriorates system performance. A wise method may be combining anode off gas recirculation(AOGR) and cathode off gas recirculation(COGR) with POX. Thus, their influence on the coupled system of intermediate temperature SOFC and POX is researched in detail in this paper. Results show that the reforming process gradually changes from exothermic to endothermic as AOGR rate increases. Meanwhile, its oxygen demand declines sharply and the process can even be self-sustained without external air input at the AOGR rate of 0.5 and 0.6. The application of AOGR can improve electrical efficiency up to 51%, but at the expense of thermal efficiency. Excessive AOGR rates will result in decreased cell voltage and insufficient energy supply to the after-burner, so it should be restricted within a reasonable range and the best recommended value is 0.5. The application of COGR has little effect on fuel line parameters, so it cause little deterioration in electrical efficiency while improving thermal efficiency. Besides, cell voltage is also insensitive to it. The combination of AOGR and COGR can obtain better fuel economy and larger cogeneration scale simultaneously at the cost of a tiny electrical output power, while an optimal balance between three efficiencies is also achieved.","PeriodicalId":15579,"journal":{"name":"Journal of Electrochemical Energy Conversion and Storage","volume":null,"pages":null},"PeriodicalIF":2.5,"publicationDate":"2022-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41998426","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
