To meet the different requirements in terms of durability and reliability, the mechanical strains must be taken into account when designing the multi-cells PEMFC. A three-dimensional finite element model of a PEMFC has been developed to analyze the behavior of the deformations and corresponding stresses of fuel cell component. The effect of clamping force on the cell performances has been investigated. We show, through the obtained results, the importance of the clamping force on the intrusion of the GDL and the stress generated in the cell components: when the clamping pressure was increased from 0.2 MPa to 0.8 MPa, the GDL intrusion increase from 0.01 mm to 0,038 mm. The results also showed that the strain is important at the ends and decreases when moving towards the middle of the multi-cell PEMFC fuel cell. Finally, the increase in the number of channels affects the distribution of the stresses and the value of the intrusion noticed on the external channel and that of the central channel becomes more important. Consequently, a good management of the clamping force is indispensable to avoid obstruction of fuels and to keep a sufficient seal between the channels.","PeriodicalId":360150,"journal":{"name":"2019 International Conference of Computer Science and Renewable Energies (ICCSRE)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126800008","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unfortunately, mobility of nodes presents several challenges in the protocol design stage, especially when using highly mobile nodes. Therefore, the design of more efficient mobility handling techniques and algorithms is of great interest to meet the quality-of-service requirements. Indeed, the first step in mobility handling is to allow nodes to be aware of their movements. In this context, because of the lack of efficiency in existing mobility detection solutions, we propose in this paper an improved mechanism, namely ADMob, allowing mobile nodes to detect their mobility autonomously. In fact, by taking advantage of the two well-known metrics, RSSI and LQI, provided by the IEEE802.15.4 compatible wireless radio transceivers, three main contributions are provided in this paper: a low-cost and accurate mobility estimation mechanism based on tracking the distance change between every two peer communicating nodes, an algorithm for optimally detecting the truly mobile nodes in the network. Finally, an adaptive algorithm for dynamically adjusting the parameters of the proposed mechanism according to targeted environments. The proposal is executed at the link layer, then, by using internal trigger messages, the up-layer communication protocols, including MAC, routing and IP protocols, can benefit from the estimated mobility information. Compared with its counterparts, the experiment results revealed that the proposed mechanism has better performance in terms of accuracy, latency, flexibility and adaptability to target environments and especially with no additional energy-hardware costs.","PeriodicalId":360150,"journal":{"name":"2019 International Conference of Computer Science and Renewable Energies (ICCSRE)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129546968","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study suggest a novel Fuzzy logic controller to control and regulate the DC-bus voltage at its reference value under changing irradiance levels. Moreover, a fuzzy logic algorithm is employed to extract the maximum power from the photovoltaic array and to provide the reference value of DC-bus voltage. Thus, a comparative analysis between the proposed and proportional integral controllers is made to prove the effectiveness of the developed controller. Furthermore, to validate the superiority of the proposed Fuzzy Logic controller, simulations were carried out at Matlab/Simulink environment. Finally, the simulation results prove that the proposed controller gives better performance in response time, rate of overshoot and tracking efficiency regarding the proportional integral controller. In addition, a comparison in term of Total Harmonic Distortion of current is asses, it demonstrate that the control strategy with the developed Fuzzy Logic gives less value compared to that with the PI controller.","PeriodicalId":360150,"journal":{"name":"2019 International Conference of Computer Science and Renewable Energies (ICCSRE)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132410688","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
