Method for fabricating membrane electrode assembly

摘要

Two catalyst electrode layers (CEL) are separately formed on two surfaces of a proton exchange membrane (PEM). The structure and processes are simple in the present invention for obtaining a membrane exchange assembly (MEA) with its thickness controllable. The MEA obtained can have a structure of CEL+PEM+CEL′. If a gas diffusion layer (GDL) is added before obtaining the CEL, a MEA having a structure of GDL+CEL+PEM+CEL′+GDL′ is obtained.
