A connection (20) for fuel cell assemblies is disclosed. The connection includes compliant members connected to individual fuel cells and a rigid member connected to the compliant members. Adjacent bundles (60) or modules of fuel cells are connected together (40) by mechanically joining their rigid members. The compliant/rigid connection permits construction of generator fuel cell stacks from basic modular groups of cells of any desired size. The connections can be made prior to installation of the fuel cells in a generator, thereby eliminating the need for in-situ completion of the connections. In addition to allowing pre-fabrication, the compliant/rigid connections also simplify removal and replacement of sections of a generator fuel cell stack.
L'invention se rapporte à un raccord (20) pour ensembles de piles à combustible. Ce raccord comprend des éléments souples reliés aux piles à combustible individuelles et un élément rigide relié auxdits éléments souples. Des ensembles (60) ou modules adjacents de piles à combustible sont reliés entre eux (40) au moyen d'un assemblage mécanique de leurs éléments rigides. Le raccordement souple/rigide permet de former des empilements de piles à combustible de générateur à partir de groupes modulaires basiques de cellules de taille quelconque. Les raccordements peuvent être faits avant l'installation des piles à combustibles dans un générateur, ce qui permet de supprimer la nécessité d'achèvement in-situ des raccordements. Ces raccords souples/rigides rendent possible la préfabrication et ils permettent également de simplifier le retrait et le placement de sections d'un empilement de piles à combustible d'un générateur.
