The two dimensional, two-phase mathematical model was developed for the cathode of proton exchange membrane fuel cell with conventional flow field operated with air. The governing equations included conductive equation
continuity equation in porous media
the convection-diffusion equations for O2 and water vapor
and the transfer equation for liquid water.The concentration of O2 and water vapor
the current density and liquid water saturation in the diffuser were calculated.The mechanism of H2O transport in the cathode diffuser and the gaseous species concentration distribution in the diffuser were studied.
