3D multiphysics numerical simulation of PEMFC with serpentine flow field

A 3D multiphysics modeling of a PEMFC with serpentine flow field design was demonstrated in this paper.Based on multiphysics and adopting four application models of COMSOL Mutiphysics,the model used current balances,mass transport equations and momentum transport to simulate a PEM fuel cell cathode's behavior,and it analyzed the distribution of pressure,gas mass fraction,gas velocity and electric current density on the cathode side of MEA,which provided all-sided analysis and theoretic support for the design of PEMFC with serpentine flow field.Finally,with the improvement of the design,the flood phenomenon was avoided.
