Electrochemical Promotional Role of Under-Rib Convection-Based Flow-Field in Polymer Electrolyte Membrane Fuel Cells

摘要: Literature data on the promotional role of under-rib convection for polymer electrolyte membrane fuel cells (PEMFCs) fueled by hydrogen and methanol are structured analyzed, with aim providing a guide to improve cell performance through optimization flow-field interaction. Data presented both physical electrochemical showing reactant mass transport, reaction, water behavior, power density enhanced convection. Performance improvement studies ranging from single stack measuring real operating conditions large-scale setups. The techniques derived collected over wide range experiments modeling variety components including arrangements. Numerical models PEMFCs an emphasis transfer reaction inside cell. primarily used here as tool in parametric analysis significant design features permit experiment. Enhanced that utilizes can contribute commercializing PEMFCs.
