The Effects of Mass Transfer Parameters on the Modeling of A PEM Fuel Cell

摘要

A detailed steady-state isothermal two-dimensional model of a proton exchange membrane fuel cell has been developed. This multi-component transport model coupled with flow in porous medium, charge balance, electrochemical kinetics and water movement in the membrane was solved using a finite element method. The solution was able to show the movement of water in the membrane by electro osmotic drags, the effects of channel width and bipolar plate shoulder dimensions, porosity, and relative humidity of the inlet steam of the anode and dry air on the cathode side.
