An electrochemical generator consisting of an alternation of membrane fuel cells and cooling cells with internal circulation of liquid water is described. The fuel cells are fed in at least one of the two compartments, anodic or cathodic, with dry gas, which is humidified through the passage of water coming from the adjacent cooling cell through a metal porous separating wall. The permeated liquid water contributes to the withdrawal of the heat of reaction by evaporating at least in part inside the fuel cells.
L'invention concerne un générateur électrochimique constitué d'une alternance de piles à combustible et de cellules de refroidissement à membranes dans lequel circule de l'eau à l'état liquide. Les piles à combustible sont alimentées, dans au moins un des deux compartiments, anodique ou cathodique, par un gaz sec, qui est humidifié par passage d'eau provenant de la cellule de refroidissement adjacente à travers une paroi de séparation poreuse métallique. Le perméat liquide contribue à l'élimination de chaleur de réaction par évaporation au moins en partie à l'intérieur des piles à combustible.
