A fuel cell system includes; a fuel cell (100) which generates electricity by using a fuel gas and an oxidant gas as reaction gases; current control means (306) which controls current of a fuel cell; voltage control means (506) which controls voltage of the fuel cell; and heat value control means (600) which caluculates a heat value required by the fuel cell system and decides a target current value of the current control means and a target voltage value of the voltage control means so as to generate the calculated necessary heat amount, thereby controlling the heat value. Thus, it is possible to supply a heat required for the fuel cell system without increasing the size of the fuel cell system. |
