1. 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.
