Abstract
A method of making an alkaline membrane fuel cell assembly is disclosed. The method may include: depositing a first catalyst layer on a first gas diffusion layer to form a first gas diffusion electrode; depositing a second catalyst layer one a second gas diffusion layer to form a second gas diffusion electrode; depositing a thin membrane on at least one of: the first catalyst layer and the second catalyst layer; joining together the first and second gas diffusion electrodes to form the alkaline fuel cell assembly such that the thin membrane is located between the first and second catalyst layers; and sealing the first and second gas diffusion layers, the first and second catalyst layers and the thin membrane from all sides.
