A fuel cell cogeneration system includes a fuel cell module, a heat exchanger, a hot water tank, a circulating water channel, and an oxygen-containing gas supply channel. A circulating water heater for heating water is provided on the circulating water channel. Part of the oxygen-containing gas supply channel is provided in the circulating water heater to thereby allow air flowing through the oxygen-containing gas supply channel to be heated by receiving heat from the circulating water heater. |
