| 摘要 |
The present invention relates to a fuel cell system comprising: a fuel cell for generating electricity and heat by a reaction between hydrogen and oxygen; a heat storage tank having a heat storage heat exchange unit provided therein for performing heat exchange between heat recovered from the fuel cell and a fluid contained in the heat storage heat exchange unit; a heat media supply line and a heat media recovery line for interconnecting the fuel cell and the heat storage heat exchange unit and forming a circulation flow channel of heat media; a bypass line branched from the heat media supply line so as to be connected to the heat media recovery line; a flow channel switching means for selectively switching, to a heat storage heat exchange unit side or a bypass line side, the flow channel of the heat media flowing along the heat media supply line; and a control unit for controlling the flow channel switching means such that the flow channel of the heat media flowing along the heat media supply line is connected to the heat storage heat exchange unit side during a generating operation of the fuel cell, and the flow channel of the heat media flowing along the heat media supply line is connected to the bypass line side during the stopping of the generating of the fuel cell. |
