Review on preparation method of membrane electrode assembly (MEA) for PEMFC

Membrane electrode assembly (MEA) is the key component of PEMFC. In this paper , the structure of the MEA is introduced briefly , and the fabrication of the MEA is classified into two modes according to the difference of the support of catalyst layer (CL) , i . e. gas diffusion layer ( GDL) and proton exchange membrane ( PEM) acting as the support respectively. Both fabricating modes are reviewed systematically. The trend of the fabrication of MEA is discussed , and the mode of fabricating the CL on the PEM is considered to be the main one in the future.
