Abstract
A molten carbonate fuel cell system wherein the cathode effluent gases are utilized in an autothermal autothermal reformer, and the anode gas is not recycled.
Claims5
A fuel cell system, which comprises:
- a. a plurality of fuel cells connected electrically through a load, each cell comprising a cathode electrode, an anode electrode, an electrolyte disposed therebetween, a cathode chamber, and an anode chamber;
- b. a autothermal reformer for partial oxidation and steam reforming reactions;
- c. means for introducing fuel wherein said fuel enters the system through the autothermal reformer;
- d. means for delivering the gases from the autothermal reformer to the anode chamber;
- e. means for delivering the gases from a heat recovery means to a burner;
- f. means for introducing pre-heated air, said air being a source of oxygen and nitrogen for the system, to said burner wherein excess fuel is burned;
- g. means for delivering the resulting gases to the cathode chamber;
- h. means for delivering the effluent gases from said cathode chamber to said autothermal reformer;
- i. means for exhausting excess gases from the system;
- whereby the water produced in the anode chamber and the excess oxygen in the cathode chamber are utilized in the autothermal reformer for the partial oxidation and steam reformation reactions.
