Method for manufacturing a membrane-electrode assembly

摘要

The method involves assembling a proton-exchange membrane with a gas diffusion layer (104), and securing a surface of the gas diffusion layer with a surface of the proton-exchange membrane. Anodic electro catalytic ink is deposited (106) on another surface of the proton-exchange membrane, where the latter surface of the proton-exchange membrane is opposite to the former surface of the proton-exchange membrane. Another gas diffusion layer is assembled (108) with the proton-exchange membrane. The latter surface of the membrane is secured with a surface of the latter gas diffusion layer. The deposited anodic electro catalytic ink comprises a mixture of a catalyst in suspension in an aqueous solvent and a binder comprising a polymer in suspension in an organic solvent and consists of an ionomer, carbonaceous material and platinum.
