Abstract[English]
A high efficiency fuel cell comprising a first bipolar plate with a cathode flow field on a first face and an anode flow field on its second face, a first end and a second end, wherein the first end of the bipolar plate includes a single air inlet, a single water inlet and a hydrogen inlet, and the second end of the bipolar plate includes a single cathode fluid outlet and a hydrogen outlet. The air inlet and water inlet are fluidly connected to a cathode flow field via a cathode flow field inlet and the cathode outlet area is at least 20% larger than the water inlet and air inlet area.[French]
L'invention concerne une pile à combustible à haut rendement comprenant une première plaque bipolaire ayant un champ d'écoulement de cathode sur une première face et un champ d'écoulement d'anode sur sa seconde face, une première extrémité et une seconde extrémité, la première extrémité de la plaque bipolaire comprenant une entrée d'air unique, une entrée d'eau unique et une entrée d'hydrogène, et la seconde extrémité de la plaque bipolaire comprenant une sortie de fluide de cathode unique et une sortie d'hydrogène. L'entrée d'air et l'entrée d'eau sont en communication fluidique avec un champ d'écoulement de cathode par l'intermédiaire d'une entrée de champ d'écoulement de cathode et la zone de sortie de cathode est supérieure d'au moins 20% à la zone d'entrée d'eau et d'entrée d'air.
