  Abstract

Direct coating of catalyst layer on the Nafion membrane has been optimized in the process of fabrication of membrane electrode assembly (MEA) to enhance the performance of direct methanol fuel cell (DMFC). In this method, the contact resistance at the interface of the catalyst layer and the membrane was found to be low. The effect of catalyst loading, thickness of membrane and the gas diffusion layer (GDL) with or without the presence of micro-porous layer (MPL) on the performance of the MEA was also investigated. The MEA fabricated by the above-mentioned method exhibited a performance of 147 mW/cm2 and 100 mW/cm2 at 80℃ and 60℃, respectively, with the catalysts loading of 4 mg/cm2.
