Abstract
A method of operating a fuel cell system includes vaporizing a liquid fuel in a vaporizer located in a hot box using heat generated by the fuel cell system to form a fuel vapor, and providing the fuel vapor to a stack of fuel cells located in the hot box to generate power.
Claims14
A fuel cell system, comprising:
- a stack of fuel cells located in a hot box;
- an anode exhaust conduit configured to receive an anode exhaust generated by the stack;
- a vaporizer located in the hot box and configured to vaporize a liquid fuel using heat generated by the fuel cell system to form a fuel vapor;
- and
- a fuel stream conduit configured to provide the fuel vapor to the stack,
- wherein the vaporizer comprises a liquid fuel heat exchanger configured to vaporize liquid alcohol using heat extracted from at least a cathode exhaust generated by the stack.
