Recently, polymer electrolyte fuel cells (PEFC) have been developed actively in many research laboratories and companies as an environment-friendly power source. One of the important factors determining the performance of a PEFC is a membrane electrode assembly (MEA). In this study, various making processes of MEA were tested and the effect of the MEA on the performance of a PEFC was investigated experimentally. As a result, an original, easy making process (Cast Process) of a high performance MEA with three-dimensional catalyst layer was contrived.
