The effect of the current density and fuel cell temperature, humidified temperature of cathode and anode, porosity of porous diffusion layer on the results mentioned above are discussed.
Reasonable designs of the structure parameters of PB layer and the gate-cathode geometry are obtained by numerical iteration and an equivalent current model.
