CA 2746372

In solid polymer fuel cells employing framed membrane electrode assemblies, a conventional anode compliant seal is employed in combination with a cathode non-compliant seal to provide for a thinner fuel cell design, particularly in the context of a fuel cell stack. This approach is particularly suitable for fuel cells operating at low pressure.

Selon l'invention, dans des piles à combustible à polymère solide faisant intervenir des ensembles membrane-électrodes à cadre, un joint souple d'anode classique est employé en combinaison avec un joint non souple de cathode pour obtenir un modèle de pile à combustible plus mince, en particulier dans le contexte d'un empilement de pile à combustible. Cette approche est particulièrement appropriée pour des piles à combustible fonctionnant à basse pression.
