Abstract

Solid-polymer electrolyte direct methanol fuel cells(SPE-DMFCs) employing carbon-supported Pt–Fe as oxygenreduction catalyst to mitigate the effect of methanol on cathode performance while operating with oxygen or air have been assembled. These SPE-DMFCs provided maximum power densities of 250 and $120mW cm^{-2}$ at $85^ oC$ on operating with oxygen and air, respectively. The polarization data for the SPE-DMFCs and their constituent electrodes have also been derived numerically employing a model based on henomenological transport equations for the catalyst layer, diffusion layer and the membrane electrolyte.
