Abstract:
1. A hybrid fuel cell including one or more electrochemical cell units, said electrochemical cell units each comprising: an auxiliary electrode having a first side and a second side; a first anode pair and a second anode pair, said first and second anode pairs each comprising two anodes having a hydrogen interface and an electrolyte interface, said anodes in said first anode pair and said second anode pair being separated by a hydrogen distribution plate disposed between said anodes such that said hydrogen interfaces of said anodes face each other and the electrolyte interfaces face outward from said first anode pair and said second anode pair, said hydrogen distributor plates being adapted to receive and distribute a supply of hydrogen across said hydrogen interfaces of said anodes; a first cathode and a second cathode, said first cathode and said second cathode each having an oxygen contacting surface and an electrolyte contacting surface; a first battery separator and a second battery separator; and a first gas distributor plate and a second gas distributor plate; said auxiliary electrode being positioned such that said first battery separator is disposed adjacent to said first side of said auxiliary electrode and said second battery separator is disposed adjacent to said second side of said auxiliary electrode; said first anode pair being disposed adjacent to said first battery separator opposite said auxiliary electrode and said second anode pair being disposed adjacent to said second battery separator opposite said auxiliary electrode; said first electrolyte distributor plate being disposed adjacent to said first anode pair opposite said first battery separator and said second electrolyte distributor plate being disposed adjacent to said second anode pair opposite said second battery separator, said first cathode being disposed adjacent to said first electrolyte distributor plate opposite said first anode pair such that said electrolyte contacting surface of said first cathode faces said first anode pair and said second cathode being disposed adjacent to said second electrolyte distributor plate opposite said second anode pair such that said electrolyte contacting surface of said second cathode faces said second anode pair.
