Item type:Publication, Effect of Flow Pattern on Single and Multi-stage High Temperature Proton Exchange Membrane Fuel Cell Stack Performance(2014-01-01); Arpronwichanop, AmornchaiA high-temperature proton exchange membrane fuel cell (HT-PEMFC) is a promising clean and effective technology for power generation because of its simplified water and heat management as well as high CO tolerance. Therefore, it could be possible to directly use a reformate gas for HT-PEMFC without the need for sophisticated purification processes. Due to the non-uniform of H<inf>2</inf> and CO distributions within fuel cells, the stack design is one of the key factors to enhance the performance and efficiency of HT-PEMFC. In this study, a single HT-PEMFC stack is investigated by considering the CO poisoning effect. The mathematical model of HT-PEMFC based on the electrochemical reaction model coupled with the diffusion model of a gas diffusion layer and electrolyte film layer is used for simulation studies. At high fuel utilization, hydrogen is highly consumed and CO concentration increases, having a significant impact on cell performance. The multi-stack HT-PEMFC is designed to minimize the CO poisoning effect and to maximize its efficiency. The power output that is obtained from each cell stack is presented and the overall power output is compared with single cell stack. Effect of different flow patterns, i.e., co-current and counter-current flow, on the HT-PEMFC stack performance is also presented. © 2014 Elsevier B.V. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Investigation of a proton-conducting SOFC with internal autothermal reforming of methane(2012-01-01); Arpornwichanop, AmornchaiIn this study, a proton-conducting SOFC (SOFC-H <sup>+</sup> ) with internal autothermal reforming of methane is proposed to overcome the carbon formation problem facing in the SOFC-H <sup>+</sup> with internal steam reforming. A one-dimensional steady-state model coupled with a detailed electrochemical model is developed to investigate the performance of the SOFC-H <sup>+</sup> (power density and fuel cell efficiency). The effect of key operating parameters such as temperature, H <inf>2</inf> O/CH <inf>4</inf> and O <inf>2</inf> /CH <inf>4</inf> feed ratios, on the SOFC-H <sup>+</sup> is also determined in this study. © 2012 Elsevier B.V. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Design and Thermal Analysis of a Solid Oxide Fuel Cell System Integrated with Ethanol Steam Reforming(2012-01-01); Arpornwichanop, AmornchaiIn this study, a thermal management of the solid oxide fuel cell (SOFC) system integrated with a steam reformer was investigated. Due to its renewable and green energy sources, ethanol was chosen as a fuel for the SOFC system in which it was converted into a hydrogen rich gas via a steam reforming. Modeling of the SOFC system was performed using a process simulator. The SOFC system performance was evaluated with respect to key operating parameters such as reforming temperature, SOFC temperature and steam to ethanol ratio. It was found that the ethanol reformer and pre-heaters require high energy consumption. To improve its thermal efficiency, the SOFC system with heat integration was analyzed and the exhaust gas from an SOFC stack was considered a useful heat source. Pinch analysis was applied to design the SOFC system with the aim to minimize the requirement of external energy sources. © 2012 Elsevier B.V. - Some of the metrics are blocked by yourconsent settings
