Title
(EN) HEAT AND WATER MANAGEMENT DEVICE AND METHOD IN FUEL CELLS
(FR) DISPOSITIF ET PROCÉDÉ DE GESTION DE CHALEUR ET D'EAU DANS DES PILES À COMBUSTIBLE
Abstract
(EN)
A method and device for fuel cell heat and water management is provided. A thermally and electrically conductive hydrophilic heat and mass transport element is provided to the fuel cell spanning from inside to outside the cell. The transport element is deposited between current collector and gas diffusion layers, where heat is transported along the transport element from an interior portion of the element inside the cell to an exterior portion of the element outside the cell. Liquid water is transported along the element into or out of the cell, and heat is removed from the exterior portion by any combination of radiation, free convection and forced convection, and where the liquid water is removed from the exterior portion by any combination of convection driven evaporation and advection. The water is added to the cell from the exterior to the interior by any combination of advection and capillary wicking.

La présente invention concerne un procédé et un dispositif de gestion de chaleur et d'eau pour des piles à combustible. Un élément hydrophile de transfert de chaleur et de masse conducteur de chaleur et d'électricité est prévu pour la pile à combustible s'étendant depuis l'intérieur jusqu'à l'extérieur de la pile. L'élément de transfert est déposé entre un collecteur de courant et des couches de diffusion de gaz, la chaleur étant transférée le long de l'élément de transfert depuis une partie intérieure de l'élément se trouvant dans la pile vers une partie extérieure de l'élément se trouvant hors de la pile. De l'eau liquide est transférée le long de l'élément dans et hors de la pile, et la chaleur est éliminée depuis la partie extérieure par toute combinaison de rayonnement, de convection libre et de convection forcée, l'eau liquide étant éliminée depuis la partie extérieure par toute combinaison d'évaporation et d'advection entraînée par la convection. L'eau est ajoutée à la pile depuis l'extérieur vers l'intérieur par toute combinaison d'advection et de pénétration capillaire.
