A component for use in assembling a membrane electrode assembly comprises a microporous layer supported on a transfer substrate, wherein the microporous layer comprises carbon particles and a hydrophobic polymer, and a polymer layer is present on the microporous layer. A process for preparing a component for use in assembling a membrane electrode assembly includes forming the microporous layer on the transfer substrate and applying a polymer layer on the microporous layer. The microporous layer may also be deposited onto a gas diffusion substrate for use in the membrane electrode assembly. |
