Abstract
The performance of Polymer Electrolyte Membrane Fuel Cells (PEMFC) such as the temperature distribution, current output, and power output will be affected by a few factors. For instances, geometry design and flow configuration of PEMFC. The aim of this study is to optimize the performance of PEMFC by determining the optimal number of flow channels and the best flow configuration. 8, 11, 15 channels were designed with various flow configurations such as co flow, counter flow and cross flow and the study was carried out by using the CFD simulation method. The materials for the electrolyte membrane and gas diffusion layer are Nafion and carbon paper. The effect of flow configuration on the temperature distribution 15 channel with cross-flow configuration obtained a better thermal performance because 15-channel with cross-flow has the lowest temperature difference of 0.048% compared to 8 and 11 channel. Moreover, 8 channels with counter-flow generates highest current density with 5582.330 A/m². However, the temperature contour is not the most uniform as compared to 11 and 15 channel. In conclusion, 11 channel with cross-flow configuration optimizes the performance with a promising electrical performance which shows maximum current density of 4103.920 A/m² and significant balance of temperature contour.
