Title (EN) IMPROVEMENT IN MASS TRANSPORT FOR TERNARY REACTION OPTIMIZATION IN A PROTON EXCHANGE MEMBRANE FUEL CELL ASSEMBLY AND STACK ASSEMBLY
(FR) AMELIORATION DU TRANSFERT DE MATIERE PAR OPTIMISATION DES REACTIONS TERNAIRES DANS UN ENSEMBLE DE PILES A COMBUSTIBLE A MEMBRANE D'ECHANGE DE PROTONS ET ENSEMBLE EMPILE
Abstract: front page image
(EN)An improved proton exchange membrane fuel cell assembly and fuel cell stack assembly are provided for the economical and efficient production of electricity. The present invention comprises improved flow fields and reactant supply systems, which provide improved and more efficient mass transport of the reactants in the fuel cell and the fuel cell stack assembly. The improved flow fields comprise three-dimensional open-cell foamed metals that are preferably plated with gold, Iridium, copper or silver. The foamed material may comprise nickel, nickel alloys, gold, gold alloys, copper or copper alloys. It may have corrugations, the corrugated structure creating microchannels. The improved reactant supply comprises an improved distribution frame to house fuel cells wherein the reactants are directly connected to the improved flow fields.
(FR)L'invention concerne un ensemble amélioré de piles à combustible à membrane d'échange de protons et un ensemble empilé de piles à combustible destinés à la production d'électricité économique et rentable. L'invention comporte des champs d'écoulement améliorés et des sources de réactifs, qui permettent un meilleur et plus rentable transfert des réactifs dans la pile à combustible et dans l'ensemble empilé de piles à combustible. Les champs d'écoulement améliorés comportent des métaux expansés à alvéoles ouverts tridimensionnels qui sont de préférence plaqués or. La source de réactifs améliorée comporte un cadre de répartition amélioré permettant de loger les piles à combustible, les réactifs étant alors directement raccordés aux champs d'écoulement améliorés.
