Abstract: Some aspects of the invention may be directed to a catalyst layer for anodes of Alkaline Exchange Membrane Fuel Cells (AEMFC). Such catalyst layer may include catalyst nanoparticles and an ionomer. Each catalyst nanoparticle may include one or more nanoparticles of catalytically active metal supported on at least one nanoparticle of crystalline RuO2. The diameter of the at least one nanoparticle of the crystalline RuO2 may be about order of magnitude larger than the diameter of the one or more nanoparticles of catalytically active metal.

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.
