摘要: A computational simulation was conducted by using a one-dimensional isothermal model for an alkaline fuel cell (AFC) single to investigate influences of the thicknesses separator, catalyst layer, and gas-diffusion layer in AFC. The polarizations were predicted at various their also analysed. Thickening separator decreased limiting current density increased slope ohmic polarization region. Investigation on thickness anode showed that optimum varied between 0.04–0.15 mm according voltage. cathode significantly influenced performance. Also, limitation effect observed. This considered be caused mass transfer resistance electrolyte.
