Abstract:
A fuel cell system comprising:a housing defining an anode chamber and a cathode chamber and including a catalyst, a protonically conductive but electronically non-conductive membrane positioned between said anode chamber and said cathode chamber and a first vent in said anode chamber; a fuel chamber in gaseous communication with said anode chamber via a first valve; a water chamber in gaseous communication with said anode chamber via a second valve; and a mixing chamber having a second vent, wherein said mixing chamber is in gaseous communication with said anode chamber via a third valve, wherein said mixing chamber receives fuel from said fuel chamber through a fuel valve, water from said water chamber via a water valve, and liquid effluent from said anode chamber via a liquid effluent valve, and said mixing chamber provides a fuel mixture to said anode chamber via a fuel mixture valve.
