Abstract: A high-temperature operation fuel cell system includes a cell stack; a reformer; a raw material supplier supplying a raw material to the reformer; a water supplier supplying reforming water; an air supplier supplying electric power generation air; a combustion chamber in which an off-gas from the cell stack is combusted and which heats the cell stack and the reformer; an igniter igniting the off-gas in the combustion chamber; and a controller. In a start-up sequence, the controller controls so that the raw material is supplied to the reformer, the electric power generation air is supplied to the cell stack, the off-gas is ignited by the igniter, and after the ignition, the supply of the reforming water is started, and after the supply of the reforming water is started, the controller further controls the air supplier to increase the flow rate of the electric power generation air in a stepwise manner.
