摘 要:Key words,: Two 1-D dynamical and isothermal models of cathode gas diffusion layer(GDL) with isobaric and non-isobaric operations for polymer electrolyte fuel cells(PEFCs) were developed and implemented in COMSOL Multiphysics *** artificial diffusion coefficient was introduced as well to make the numerical computation be *** the non-isobaric model,the pressure of gas mixture was obtained by summing up the governing equations of gaseous components,instead of Navier-Stoks *** of the two models were carried out with the steady-states and dynamical simulations under given *** corresponding analysis based on the simulated results was also given *** paper is contributed to finding the differences between the isobaric and non-isobaric operation in the two-phase model of cathode GDL.
