Patent ID: 8685576

Claim:
A fuel cell, comprising: a membrane electrode assembly including a membrane, a hydrogen electrode and an oxygen electrode, a hydrogen compartment disposed on one side of the hydrogen electrode and an oxygen compartment disposed on one side of the oxygen electrode; an electrically conductive, porous, hydrophilic membrane having a bubble pressure of about 10 Psid to about 100 Psid being disposed on one side of the oxygen compartment opposite from the oxygen electrode and acting as a gas/liquid separator, the electrically conductive, porous, hydrophilic membrane comprising material selected from a group of polyethersuflone and other plastics in inherently hydrophilic or modified to instill a hydrophilic property wherein the electrically conductive, porous, hydrophilic membrane having a pore size of between about 0.05 micron to 0.5 micron; and a low pressure water compartment is disposed on one side of the electrically conductive, porous, hydrophilic membrane opposite from oxygen compartment.
