A fuel cell vehicle comprising: a hydrogen injector configured to open when a current larger than or equal to a predetermined current threshold (Ith) is supplied to the hydrogen injector; a controller configured to control the current which is supplied to the hydrogen injector such that the current supplied to the hydrogen injector follows a target current value, the target current value being an initial target current value (Irl) which is higher than the predetermined current threshold (Ith); a first power supply configured to supply electric power to the hydrogen injector and a prescribed auxiliary; a second power supply having an output voltage which is higher than an output voltage of the first power supply; and a voltage converter configured to step down the output voltage of the second power supply and supply electric power to the first power supply, wherein - when the controller detects at least one of a first start signal for starting the prescribed auxiliary other than the hydrogen injector and a second start signal for informing startup of the prescribed auxiliary other than the hydrogen injector, and when at the same time - the controller is configured to increase the initial target current value (Irl) to an increased target current value when an output voltage of the voltage converter is equal or lower than the output voltage of the first power supply, - the controller is configured not to increase the target current value when an output voltage of the voltage converter exceeds the output voltage of the first power supply. a controller configured to control the current which is supplied to the hydrogen injector such that the current supplied to the hydrogen injector follows a target current value, the target current value being an initial target current value (Irl) which is higher than the predetermined current threshold (Ith); a first power supply configured to supply electric power to the hydrogen injector and a prescribed auxiliary; a second power supply having an output voltage which is higher than an output voltage of the first power supply; and a voltage converter configured to step down the output voltage of the second power supply and supply electric power to the first power supply, wherein - when the controller detects at least one of a first start signal for starting the prescribed auxiliary other than the hydrogen injector and a second start signal for informing startup of the prescribed auxiliary other than the hydrogen injector, and when at the same time - the controller is configured to increase the initial target current value (Irl) to an increased target current value when an output voltage of the voltage converter is equal or lower than the output voltage of the first power supply, - the controller is configured not to increase the target current value when an output voltage of the voltage converter exceeds the output voltage of the first power supply. - when the controller detects at least one of a first start signal for starting the prescribed auxiliary other than the hydrogen injector and a second start signal for informing startup of the prescribed auxiliary other than the hydrogen injector, and when at the same time - the controller is configured to increase the initial target current value (Irl) to an increased target current value when an output voltage of the voltage converter is equal or lower than the output voltage of the first power supply, - the controller is configured not to increase the target current value when an output voltage of the voltage converter exceeds the output voltage of the first power supply.
