Abstract
A fuel cell system wherein a fuel conditioner supplied with fuel and with exhausted cathode gas is adapted to partially oxidize a portion of the fuel with the cathode exhaust gas and to utilize at least the water in the oxidation products and at least the water in the cathode exhaust gas to steam reform a portion of the fuel to produce fuel process gas.
Claims39
A fuel cell system comprising:
- a fuel cell including an anode section for receiving fuel process gas and a cathode section for receiving oxidant process gas;
- and means for receiving a supply of fuel and gas exhausted from said cathode section for oxidizing a portion of said fuel with said cathode exhaust gas and for converting a portion of said fuel to said fuel process gas by directly utilizing said oxidized portion of fuel, said converting being with at least the water in the products in said cathode exhaust gas and at least the water in the products in said oxidized portion of fuel.
A process in which fuel process gas and oxidant process gas are introduced into anode and cathode sections, respectively, of a fuel cell and further comprising:
- oxidizing a portion of supply fuel with gas exhausted from said cathode section;
- and converting a portion of said fuel to said fuel process gas by directly utilizing said oxidized portion of fuel, said converting being with at least the water in the products in said cathode exhaust gas and at least the water in the products in said oxidized portion of fuel.
