The effect of inlet gas velocities of hydrogen and air on high temperature PEM fuel cell performance. The effect of conductivity of polymeric membrane on high temperature Multiphysics modeling using comsol pdf fuel cell performance.
Modeling of high temperature PEM fuel cell by Comsol Multiphysics. A consistent and systematic mathematical model is developed in order to study the effect of these parameters. The model is applied to an isothermal, steady state, three-dimensional PEM fuel cell in order to observe concentration profiles, current density profiles and polarization curves. The model includes the transport of gases in anode and cathode gas flow channels, diffusion in the catalyst layers, the transport of water and hydronium ion in the polymer electrolyte and in the catalyst layers, and the transport of electrical current in the solid phase. The model is considered as having a single flow channel. The simulation is performed by using licensed Comsol Multiphysics 5.
C for ohmic and activation regions. The best match with the experimental data is obtained when the inlet hydrogen gas velocity is 0.

With point electric source as example, this paper describes direct current method forward modeling with COMSOL Multiphysics. By comparing and analyzing COMSOL Multiphysics modeling results and theoretic values of typical models, the validity and feasibility of direct current method forward modeling based on COMSOL Multiphysics is proved. Due to the powerful mesh dissection, solution function and abundant post process operation, it shows an important significance of applying COMSOL Multiphysics in geophysical modeling.
