A fuel cell system control device includes a carbon amount determination unit for determining the carbon amount in fuel gas supplied to a fuel cell stack depending on required output of the stack, a temperature detector unit for detecting temperature of a steam reformer and temperature of an evaporator, an S/C determination unit for determining a range of steam/carbon ratio based on the temperature of the steam reformer, a water supply amount determination unit for determining a range of the water supply amount to the evaporator based on the carbon amount and the steam/carbon ratio, an evaporator operating state determination unit for determining whether the temperature of the evaporator is a temperature determined based on the range of the water supply amount, and a reformer control unit for controlling the steam reformer and a partial oxidation reformer based on the result of the evaporator operating state determination unit. |
