Title (EN) PROTON EXCHANGE MEMBRANE FUEL CELL BIPOLAR SEPARATOR PLATE
(FR) PLAQUE SEPARATRICE BIPOLAIRE DE CELLULE ELECTROCHIMIQUE A MEMBRANE ECHANGEUSE DE PROTONS
Abstract:
(EN) A gas impervious bipolar separator plate (39) for a proton exchange membrane fuel cell (20) having at least one electronically conductive material in an amount in a range of about 50 % to about 95 % by weight of the separator plate, at least one resin in an amount of at least about 5 % by weight of the separator plate, and at least one hydrophilic agent, where the electronically conductive material, the resin, and the hydrophilic agent are substantially uniformly dispersed throughout the separator plate.
(FR) L'invention a trait à une plaque séparatrice bipolaire imperméable au gaz (39) pour cellule électrochimique à membrane échangeuse de protons (20) renfermant au moins un matériau à conductivité électronique selon une quantité s'échelonnant entre environ 50 et 95 % du poids de la plaque séparatrice, au moins une résine selon une quantité représentant au moins 5 % du poids de la plaque séparatrice, et au moins un agent hydrophile. Le matériau à conductivité électronique, la résine et l'agent hydrophile sont répartis de manière sensiblement uniforme sur toute la plaque séparatrice.
