Abstract
A method for making fuel cell membrane electrode assembly is provided. In the method, a porous template having a number of holes and a proton exchange membrane is provided. A number of tube carriers having electron conductibility are formed. Each tube carrier is formed in one hole of the porous template. A number of catalyst particles are uniformly adsorbed on inner walls of the tube carriers. Proton conductor is filled in the tube carriers having catalyst particles adsorbing thereon. The proton exchange membrane is sandwiched between the two porous templates to form a laminated structure. The laminated structure is hot pressed. The porous templates are removed from the hot pressed laminated structure.
