Abstract
A fuel cell system includes a power supply controller. In response to input of a first command prior to a start of fuel cells in a state of power supply from a power source to fuel cell-related auxiliary machinery, the power supply controller reduces an amount of electric power supplied to the fuel cell-related auxiliary machinery until input of a start instruction to start the fuel cells. In response to input of a second command, the power supply controller instructs to continue the power supply from the power source to the fuel cell-related auxiliary machinery without reducing the electric power level of the power supply, irrespective of the input or non-input of the first command. The fuel cell system of this arrangement effectively reduces the amount of electric power consumed by an electricity storage device before a start of the fuel cells.
