Phosphoric Acid Fuel Cells (PAFCs) are widely recognized for their stability and suitability in stationary power generation applications. A crucial factor affecting PAFC performance is the flow field design, which influences reactant gas distribution, water removal, and pressure drop. Poor flow field configurations can result in concentration gradients, localized flooding, and efficiency losses. This study utilizes Computational Fluid Dynamics (CFD) to analyze and optimize various PAFC flow field geometries, including serpentine, parallel, and interdigitated designs. Through the solution of coupled momentum, species transport, and energy equations, the simulation provides insight into flow uniformity, reactant utilization, and pressure dynamics. Results show that modified serpentine and interdigitated patterns significantly enhance gas distribution and reduce pressure losses compared to conventional designs. These improvements lead to better electrochemical performance and longer fuel cell lifespan. The findings demonstrate the effectiveness of CFD as a predictive and optimization tool for next-generation PAFC development.
