Abstract:
1. A fuel cell system comprising: a fuel cell module having a solid-oxide fuel cell and a reformer configured to perform steam reforming of a fuel gas supplied to the solid-oxide fuel cell; a water supplying unit having a water storage tank storing water to be supplied to the reformer, a pump to pump the water stored in the water storage tank to the reformer, and a flow rate detecting unit to detect an amount of the water supplied to the reformer by the pump; a control unit is programmed to control the water supplying unit, at least during start up of the fuel cell system, in switching the pump from a stop state to a pumping state to start pumping the water, the control unit is further adapted to shift to a normal control state after performing a start-operation-control to set a feeding flow rate of the pump to a rate higher than the feeding flow rate during the_normal control state for a predetermined time, the control unit is further programmed to execute the start-operation-control for setting a feeding flow rate of the pump higher than the feeding flow rate during a normal control state for a predetermined time during a start of auto thermal reforming.
