A fuel cell system capable of stably supplying hot water to a load is provided. The fuel cell system includes a solid-oxide fuel cell 31, a heat exchanger 40 that exchanges heat between an exhaust gas from the solid-oxide fuel cell 31 and water, a hot water storage tank 42 that reserves the water, circulation pipes 43a and 43b for circulating the water between the hot water storage tank 42 and the heat exchanger 40, and a circulation pump 41 provided to the circulation pipes 43a and 43b. The fuel cell system is provided with a controller 39 that controls the fuel utilization ratio during power generation by the solid-oxide fuel cell 31 in accordance with the used amount of reserved hot water. |
