Abstract
The proton exchange membrane fuel cell (PEMFC) technology is one of most clean Power and producing devices that have high efficiency. The PEMFC is very complex system, the operating principles is based on thermodynamics, electrochemistry, hydrodynamics and mass transfer theory. Consequently, complete mathematical model is difficult. PEMFC performance is directly proportional to the flow channel design on bipolar plates. So, bipolar plates have been studied theoretically and experimentally. In modeling and simulation the COMSOL software has been used to solve Navier– Stokes equation in flow channels and Brinkman’s equation in the porous gas diffusion layer. The main effective parameters in this study were pressure drop, effective area and residence time. The data has been verified with published data. A parametric study has been carried out to study the different parameters affecting bipolar plates performance. The experimental study has been done by using fuel cell test station (850 e). Furthermore the performance of PEMFC was investigated by using different bipolar plate designs as parallel or straight bipolar plate, two, three and six passes header serpentine flow channels, two, three and six passes serpentine flow channels with square bend, two, three and six passes serpentine flow channels with curvilinear bend and spiral design.
