Abstract
Electrochemical cell comprises, in one embodiment, a proton exchange membrane (PEM), an anode positioned along one face of the PEM, and a cathode positioned along the other face of the PEM. An electrically-conductive, compressible, spring-like, porous pad for defining a fluid cavity is placed in contact with the outer face of the cathode or the outer face of the anode. The porous pad comprises a particulate or mat of one or more doped- or reduced-valve metal oxides, which are bound together with one or more thermoplastic resins.
