METHOD FOR MANUFACTURING MEMBRANE ELECTRODE ASSEMBLY

摘要

Disclosed is a method for manufacturing a membrane electrode assembly wherein a fuel cell electrode layer is formed on a material and is transferred to a fuel cell electrolyte membrane. The method includes the steps of: forming a fuel cell electrode layer on a first substrate layer; cutting from the fuel cell electrode layer side using cutting means so as to reach a second substrate layer, and forming a cut of a predetermined shape in the fuel cell electrode layer and the first substrate layer; and a removal step for peeling off an outer side portion of the predetermined shape from the second substrate layer.
