Abstract:
An electrolyte reservoir layer disposed behind and adjacent one of the catalyst layers of a fuel cell is porous and hydrophilic to the electrolyte. In one embodiment the reservoir layer includes impregnations of hydrophobic material to provide reactant gas passages through the reservoir layer to the catalyst layer. Additionally the reservoir layer includes impregnations of a material similar to the fuel cell electrolyte retaining matrix material to improve electrolyte transfer from the matrix into the reservoir. The impregnations of hydrophobic material are designed to provide good distribution of the reactant gas into the catalyst layer without consuming a large volume of the reservoir. In a preferred embodiment the reservoir is also the electrode substrate whereby the catalyst layer is bonded to the surface thereof.
