Abstract
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.
Claims18
An electrochemical generator, comprising:
- at least one membrane fuel cell and at least one cooling cell interposed between two bipolar plates,
- wherein said at least one membrane fuel cell comprises a cathode compartment having a reticulated reactant gas distributor and an anode compartment having a reticulated reactant gas distributor,
- wherein at least one gaseous reactant passes through said anode compartment and at least one other gaseous reactant passes through said cathode compartment,
- said at least one cooling cell is interposed between said at least one membrane fuel cell and one of the bipolar plates, and is separated from said cathode compartment or said anode compartment of said at least one membrane fuel cell by a porous wall, and
- liquid water passes from said at least one cooling cell to said anode or cathode compartment of said at least one membrane fuel cell across said porous wall.
