Simulation study of water content and temperature distribution in PEMFC with parallel flow channels

This study simulated water content and temperature distribution in a PEMFC with parallel and cooling channels. Key findings indicate that co-directional inlet flow enhances performance with higher current density and uniform temperature distribution. Increased operating pressure boosts current and temperature, while higher humidity decreases current due to flooding risks and slightly raises temperature. Optimizing pressure and humidity is crucial for balancing performance and thermal management. Future work should refine flow channel designs and validate simulations experimentally for better PEMFC application.
