Title
(EN) LARGE NON-BIPOLAR FUEL CELL STACK CONFIGURATION
(FR) GRANDE CONFIGURATION D'EMPILEMENT DE PILES A COMBUSTIBLE NON BIPOLAIRES
Abstract
(EN)
A large non-bipolar fuel cell stack configuration where non-bipolar fuel cell arrays, manufactured on reel-to-reel sheets of porous plastic substrate material, are electronically connected in parallel with air and/or oxidizing gas flowing between the arrays. Separator plates of conventional type bipolar fuel cell stacks are eliminated in this approach and many of the electrical contact problems associated with conventional fuel cell stack are overcome. Maintenance of the system may be carried out with minimal down time since individual fuel cell modules may be diagnosed and replaced within the stack while the fuel cell system is running. The present invention enables large power fuel cells, with relatively low total mass, to be readily manufactured at low cost.
(FR)
La présente invention concerne une grande configuration d'empilement de piles à combustible non bipolaires dans laquelle des réseaux de piles à combustible non bipolaires, fabriqués sur des feuilles à bobine de matériau substrat en plastique poreux, sont connectés électriquement parallèlement à l'air et/ou à un gaz oxydant s'écoulant entre les réseaux. En outre, des plaques de séparation d'empilement de piles à combustible non bipolaires de type classique sont éliminées dans cette approche, et plusieurs problèmes liés au contact électriques associés à l'empilement de cellules à combustible classique sont résolues. Par ailleurs, l'entretien de ce système peut être effectué avec un minimum de temps d'arrêt puisque les modules de piles à combustible individuels peuvent être diagnostiqués et remplacés à l'intérieur de l'empilement alors que le système est en marche. En l'occurrence, cette invention permet de fabriquer facilement et à faible coût des piles à combustible très puissantes présentant une masse totale relativement faible.
