Title (EN) SELF-THAWING FUEL CELL
(FR) PILE A COMBUSTIBLE A DEGEL AUTOMATIQUE
Abstract: front page image
(EN)Electrical resistance heating elements (42, 44) recessed in the terminal plates (52, 54), or the cell end plates (14, 16), of a fuel cell stack at the interfaces therebetween are energized by electricity generated by the stack to heat the end cells (7, 9) during start-up of a frozen stack. The flow of current in the heating elements (42, 44) is ended when the temperature of the end cell(s) (7, 9) reach(es) a prescribed above-freezing temperature.
(FR)L'invention concerne des éléments chauffants de résistance électrique, encastrés dans les plaques terminales ou les plaques terminales de piles d'un paquet de piles à combustible, qui sont alimentés aux interfaces situées entre, par de l'électricité produite par le paquet de piles pour chauffer les piles terminales pendant le démarrage d'un paquet de piles gelées. Le flux de courant circulant dans les éléments chauffants s'arrête lorsque la température de la (des) pile(s) terminale(s) atteint une température hors gel prescrite.
