An electrolyte reservoir layer disposed behind and adjacent one of the catalyst layers of a fuel cell is a porous, hydrophilic material. Excess liquid volume wicks into the reservoir layer through the catalyst layer and fills the smaller pores within the reservoir. The larger pores remain empty and provide clear passageways for the reactant gas to reach the catalyst. Wetproofing of the reservoir layer is not required. In a preferred embodiment the reservoir layer is the electrode substrate whereby the catalyst layer is bonded to the surface thereof. |
