dc.description.abstractAn energy analysis for the H3PO4 (phosphoric acid) doped PBI (polybenzimidazole) polymer electrolyte membrane fuel cell depending on the operating temperature is aimed in this study. In line with this aim, the relation of heat sources from electrochemical reaction, ionic and electronic current with the cell operating temperature is analyzed in detail for both anode catalyst layer and cathode catalyst layer. In addition, effect of the cell operating temperature on species and charge in the fuel cell is indicated. For this analysis, a single phase and two dimensional numerical model is developed with the help of COMSOL Multiphysics 4.2a software under the conditions of the different cell operating temperatures (from 120 to 180 degrees C stepping by 20 degrees C) and a constant acid doping level (6.75 RPU H3PO4/PBI). The results bring out that the irreversible and reversible entropic heat sources are more dominant than the joule heating source and the heat source by conduction at the cathode catalyst layer. The molar concentrations of all species through all layers are also presented. (C) 2016 Elsevier Ltd. All rights reserved.
