The purpose of this study is to clarify an effect on forming method of catalyst layer on the degradation characteristics of MEA (membrane electrode assembly). MEA performance is one of the important factors for the performance of PEFC (polymer electrolyte fuel cell). To improve the degradation characteristics of the MEA is possibly to contribute on improving the durability of the PEFC. In comparison with a conventional screen method for forming the catalyst layer, a spray method was able to suppress 8.6% reduction in power density. For the catalyst layer number, to increase the number of cathodes was possibly to suppress the degradation.
