Oxygen diffusion transport and electrochemical reaction in the oxygen cathode of direct methanol fuel cell ( dmfc ) have been expressed with the tffa model. model calculation has been carried out to investigate the effects of structural parameters of the dmfc cathode on the electrode performance, which is respectively represented by the curve of cathode overpotential versus current density. much attention has been paid to parameters including the porosity of the reaction layer, the thickness of the thin - film on the flooded - agglomerate, the radius of the flooded - agglomerate, the volume fraction of the flooded - agglomerates in the reaction layer
