▎ 摘 要
NOVELTY - The manufacturing method involves forming gas diffusion layer (40) comprising graphene on microporous layer (30) using printer (42). The microporous layer forms interface between the catalyst layer and gas diffusion layer. The gas diffusion layer is formed with different areas having different porosities from different feedstocks (43,44). The feedstocks have particles of different properties such as different particle size distribution. USE - Manufacturing method of membrane electrode assembly (claimed) for fuel cell. ADVANTAGE - Membrane electrode assembly is manufactured and used for efficient operation and construction of the fuel cell. Graphene provides high conductive and hydrophobic properties to the gas diffusion layer. Different feedstocks provide control in forming the sub-layers of the gas diffusion layer in various dimensions such as three dimensions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a membrane electrode assembly for fuel cell. DESCRIPTION OF DRAWING(S) - The drawing shows the schematic view of the gas diffusion layer and its formation.
