    摘要： Problem to be Solved
    The present invention provides a water content estimation apparatus for a fuel cell and a fuel cell system which are capable of accurately determining a water content in a cell plane.
    Solution
    The water content estimation apparatus for a fuel cell includes an estimating unit for estimating a residual water content distribution in a reactant gas flow channel and a moisture content distribution in an electrolyte membrane in a cell plane of a single cell while taking into consideration water transfer that occurs between an anode electrode and a cathode electrode via the electrolyte membrane between the anode electrode and the cathode electrode. The fuel cell system performs control based on an estimation result by the estimating unit so that the fuel cell assumes a predetermined water condition.

    摘要： A fuel cell system comprises: a fuel cell formed of a plurality of cells stacked therein, each cell generating electric power through an electrochemical reaction between a fuel gas and an oxidant gas; a cell monitor capable of detecting a group voltage for each group wherein each group is composed of two or more cells; and an estimation device that estimates a minimum cell voltage. The estimation device comprises a maximum cell voltage estimation part that estimates a maximum cell voltage, and the estimation device estimates the minimum cell voltage by using an estimated value of the maximum cell voltage and a minimum group-average voltage, where an average voltage of a group having the lowest voltage value among the group voltages is defined as the minimum group-average voltage.

    摘要： A fuel cell system includes: a power supply circuit including a fuel cell (100) and a secondary battery (130); an oxidant gas supply flow passage (33); a pump (320); and a control unit (110) configured to drive the pump (320) and dilute hydrogen retained in an cathode (120, 140). The control unit (110) is configured to stop supplying an oxidant gas to the cathode (120, 140) by stopping an operation of the pump (320) such that dilution of the hydrogen retained in the cathode (120, 140) is stopped, while a fuel cell vehicle (10) remains stationary after a starter switch (115) of the fuel cell vehicle (10) is switched from an off state to an on state, or while a load required of the power supply circuit remains smaller than a predetermined value after the starter switch (115) of the fuel cell vehicle (10) is switched from the off state to the on state.
