PURPOSE: A fuel cell hybrid system is provided to efficiently use heat generated from a fuel cell while connecting the fuel cell to not only a heat engine but also an organic rankine cycle device. CONSTITUTION: A fuel cell hybrid system includes a heat engine (200) which has a compressor (210) compressing an oxidant-supplying gas, and an expander (220) expanding the oxidant-supplying gas (220); a fuel battery (100) which includes a fuel electrode (142), an air electrode (144), and a catalytic combustor; a first heat exchanger (510) enabling the oxidant-supplying gas discharged from the compressor and an air electrode exhaust gas to exchange heat; and a second heat exchanger (520) enabling the oxidant-supplying gas discharged from the first heat exchanger and the oxidant supply gas to exchange heat. |
