| Abstract: |
A hydrogen-fueled fuel cell reacts residual fuel in the exhaust of the anode flow field either in a catalytic converter or by feeding the anode exhaust into the cathode oxidant stream. Control of flow of anode exhaust into the cathode oxidant stream may be in response to a flammability sensor, a gas composition analyzer, current output, or periodically in response to a timer; the anode exhaust may be fed either upstream or downstream of the cathode air inlet blower.

First Claim:
Show all 19 claims |
We claim:
1. A fuel cell system for supplying electric power, comprising:
- an electrolyte;
- a cathode catalyst disposed between a cathode substrate and said electrolyte on one side of said electrolyte;
- an anode catalyst disposed between an anode substrate and said electrolyte on the opposite side of said electrolyte;
- a cathode flow field having an inlet for flowing an oxidant in contact with said cathode, said cathode flow field being vented to permit release of exhaust therefrom;
- an oxidant pump providing oxidant to said cathode flow field inlet;
- an anode flow field for allowing a stream of hydrogen to contact said anode, said anode flow field having an exhaust;
- a source for providing hydrogen to said anode flow field; and
- an anode flow field exhaust line connecting the exhaust of said anode flow field to a hydrogen/oxidant catalytic surface, whereby hydrogen in the exhaust of said anode flow field will be combusted.
