Abstract
A fuel cell system includes a fuel cell module having a solid-oxide fuel cell and a reformer adapted to perform steam reforming of a fuel gas supplied to the solid-oxide fuel cell, a water supplying unit and a control unit. The controller unit is adapted to control, at least during start up of the fuel cell system switching of a pulse pump from a stop state to a pumping state to start pumping of water, and to change the pulse pump to a normal control state after performing a start-operation-control which sets a feed flow rate of the pulse pump higher for a predetermined time than a feed flow rate of the water during the normal control state.
