CA 2590055

A membrane electrode assembly comprises an ion exchange membrane, an anode positioned on one side of the membrane and a cathode positioned on the other side of the membrane so that a portion of the cathode extends outside of the anode area on the oxidant outlet side of the fuel cell such that any hydrogen leaked from the anode side to the cathode side due to any defects (holes) existing in the membrane near the oxidant outlet is recombined with the oxygen on the cathode side before it reaches the oxidant outlet and no hydrogen is present in the oxidant stream exhausted from the fuel cell.

L'invention concerne un ensemble électrodes à membrane (MEA) comprenant une membrane échangeuse d'ions, une anode disposée d'un côté de la membrane, et une cathode disposée de l'autre côté de la membrane de sorte qu'une partie de la cathode s'étende en dehors de la zone anode sur le côté orifice de sortie d'oxydant de la pile à combustible. Ainsi, l'hydrogène pouvant fuir du côté anode au côté cathode à cause de défauts (trous) dans la membrane à proximité de l'orifice de sortie d'oxydant est recombiné à de l'oxygène sur le côté cathode avant qu'il atteigne l'orifice de sortie d'oxydant, de sorte qu'il n'y ait pas d'hydrogène dans le flux d'oxydant s'échappant de la pile à combustible.
