Abstract
When a time point of occurrence of a stop state of a fuel cell system is predicted during traveling, a drying state control that causes a fuel cell stack to transition to a dry state is started a predetermined time (a required drying time) before the predicted time point of occurrence of the stop state.
Claims6
A method of stopping a fuel cell vehicle equipped with a fuel cell system including a fuel cell stack, the fuel cell stack including a plurality of power generation cells stacked together, the power generation cells generating electric power by an electrochemical reaction of a fuel gas and an oxygen-containing gas, the fuel cell vehicle being configured to travel by electric power generated by the fuel cell system in an ON state of a power switch of the fuel cell vehicle, the method comprising:
- predicting a time point of occurrence of a stop state of the fuel cell system by transition of the power switch from the ON state to an OFF state during traveling;
- and
- starting a drying state control that causes the fuel cell stack to transition to a dry state, a predetermined time point before the predicted time point of occurrence of the stop state, and causes an impedance of the fuel cell stack to reach a target impedance at a time point which allows for a margin time to elapse before the predicted time point of occurrence of the stop state.

- the fuel cell vehicle comprising:
- one or more processors that execute computer-executable instructions stored in a memory, wherein the one or more processors execute the computer-executable instructions to:
- predict a time point of occurrence of a stop state of the fuel cell system by transition of the power switch from the ON state to an OFF state during traveling;
- and
- start a drying state control that causes the fuel cell stack to transition to a dry state, a predetermined time point before the predicted time point of occurrence of the stop state, and causes an impedance of the fuel cell stack to reach a target impedance at a time point which allows for a margin time to elapse before the predicted time point of occurrence of the stop state.
