Abstract: The present invention relates to a method for manufacturing a fuel cell electrode (E) by depositing a catalytic layer (2) on a diffusion layer (3), characterized in that said catalyst is deposited on the diffusion layer (3) by ionized physical vapor deposition (IPVD) in a vacuum chamber. The invention also relates to a method for manufacturing a fuel cell half-core comprising an ionic membrane (1), a catalytic layer (2) and a diffusion layer (3) by depositing the catalytic layer (2) on a support (1; 3), characterized in that said catalyst is deposited on the support (1; 3) by ionized physical vapor deposition (IPVD) in a vacuum chamber.
