Method for producing membrane electrode assembly, involves joining proton exchange membrane and gas diffusion layer together, such that catalyst layer is arranged between proton exchange membrane and gas diffusion layer

摘要

The method involves forming a catalyst layer (7,8) on a proton exchange membrane (3) and/or on a gas diffusion layer (4). The proton exchange membrane and the gas diffusion layer are joined together, such that the catalyst layer is arranged between the proton exchange membrane and the gas diffusion layer. The catalyst dispersion with the carbon nanotube (2) is generated and is applied to the proton exchange membrane and/or to the gas diffusion layer.
