Heat Transfer by Heat Generation in Electrochemical Reaction of PEMFC

摘要: GDL(Gas Diffusion Layer) is one of the main components PEM fuel cell. It transports reactants from channel to catalyst and removes reaction products channels in flow filed plate. known that higher permeability GDL can make it possible enhance gas transport through GDL, leading better performance. And MEA`s temperature determined by heat transport. In this paper, three dimensional numerical simulation cell parallel serpentine presented analysis mass transfer characteristics using a FLUENT modified include electrochemical behavior. Results show case channel, performance variation with change was not so much. This thought because carried out diffusion mechanism channel. Also, resulted convection though GDL. process changed when becomes low.
