Abstract: In a fuel cell system, the output from a plurality of fuel cells can reach an output greater than or equal to auxiliary driving power in a short time because the initial supply amount of raw fuel supplied from a raw fuel supply part is greater than or equal to a first supply amount that is a raw fuel supply amount corresponding to the auxiliary driving power. Thus, even if the raw fuel is supplied at the initial supply amount when a power failure has occurred in an electric power system during a startup operation of the fuel cell system, it is possible to supply electric power from the fuel cells to the auxiliary machinery and continue to drive the auxiliary machinery under the control of a startup controller. This suppresses the stop of the fuel cell system under the startup operation.

Abstract: A fuel cell system includes a reformer and a plurality of fuel cells of solid oxide. The reformer reforms raw fuel to generate fuel gas. The plurality of fuel cells generates electric power by using the fuel gas and oxidant gas. The plurality of fuel cells is arranged in the up-down direction and the right-left direction. The reformer has a cell facing face that faces any of the plurality of fuel cells in the back-and-forth direction. This configuration improves temperature uniformity among the plurality of fuel cells, and as a result, suppresses or prevents a decrease in the power generation efficiency of the fuel cell system.
