NOVELTY - A fuel cell (10) consists of a membrane electrode assembly (12) including a membrane (14), a hydrogen electrode (16), an oxygen electrode (18), a hydrogen compartment (20) and an oxygen compartment (22), electroconductive porous hydrophilic membrane (24) and low-pressure water compartment (26). The compartment (20) is disposed on one side of the electrode (16) and compartment (22) is disposed on one side of the electrode (18). The membrane (24) disposed on one side of the compartment (22) opposite from the electrode (18), acts as a gas/liquid separator.    USE - Fuel cell e.g. electrolysis cell (claimed) is used for membrane-based passive water management.    ADVANTAGE - The fuel cell containing the membrane has high electroconductivity and bubble pressure. The membrane of the fuel cell has excellent reliability and reduces the effectiveness of evaporator.    DETAILED DESCRIPTION - A fuel cell consists of a membrane electrode assembly including a membrane, a hydrogen electrode, an oxygen electrode, a hydrogen compartment and an oxygen compartment, electroconductive porous hydrophilic membrane and low-pressure water compartment. The hydrogen compartment is disposed on one side of the hydrogen electrode and oxygen compartment is disposed on one side of the oxygen electrode. The electroconductive porous hydrophilic membrane disposed on one side of the oxygen compartment opposite from the oxygen electrode, acts as a gas/liquid separator. The electroconductive porous hydrophilic membrane has a bubble pressure of 10-100 Psid. The electroconductive porous hydrophilic membrane comprising material is chosen from polyethersulfone or other plastics inherently hydrophilic or modified to instill a hydrophilic property. The electroconductive porous hydrophilic membrane has a pore size of 0.05-0.5 mu m. The low-pressure water compartment is disposed on one side of the electroconductive porous hydrophilic membrane opposite from oxygen compartment. An INDEPENDENT CLAIM is included for electrolysis cell.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic illustration of the membrane-based passive water management fuel cell.
