Patent

CA 2538282

The invention relates to a fuel cell comprising a membrane (1) and an electrode (3; 3'), which is associated with a metallic current collector (5) via a fibrous gas diffusion layer (7) in which the state of the surface of the metallic collector surface in contact with the diffusion layer (7) is adapted to that of the surface of the diffusion layer, typically deformed in a superficial manner by mechanical action.

L'invention concerne une pile à combustible comprenant, de part et d'autre d'une membrane (1), une électrode (3 ;3') associée à un collecteur de courant métallique (5) via une couche fibreuse de diffusion de gaz (7), dans laquelle l'état de surface de la surface du collecteur métallique en contact avec la couche de diffusion (7) est adapté à celui de la surface de la couche de diffusion, typiquement déformé superficiellement par action mécanique.
