Patent

CA 2597534

This invention provides a fuel cell comprising a cathode catalyst layer (2), an anode catalyst layer (3) comprising a perfluoro-type electrically conductive binder having an aggregate structure, in which a hydrophobic (lipophilic) group faces outward and a hydrophilic group faces inward, and a proton-conductive film (6) disposed between the cathode catalyst layer (2) and the anode catalyst layer (3).

L'invention concerne une pile à combustible comprenant une couche de catalyseur de cathode (2), une couche de catalyseur d'anode (3) et une pellicule conductrice de protons (6) disposée entre ces deux couches de catalyseurs (2, 3). La couche de catalyseur d'anode (3) comprend en outre un liant conducteur de l'électricité de type perfluoro présentant une structure en agrégats dans laquelle un groupe hydrophobe (lipophile) est orienté vers l'extérieur et un groupe hydrophile est orienté vers l'intérieur.
