A fuel cell forklift using a fuel cell unit, which includes a fuel cell system and which is replaceable by a lead-acid battery. The forklift includes a motor which generates drive force when supplied with power from the fuel cell unit or lead-acid battery. A voltmeter measures voltage of the fuel cell unit or lead-acid battery. A vehicle controller controls operation of the forklift and restricts operation when the measured voltage is less than a threshold voltage. The fuel cell unit includes a capacitor charged by the fuel cell system. A voltage conversion unit converts voltage of power from the capacitor to a target voltage, which is set to be greater than or equal to the threshold voltage, and supplies a power supply destination, which includes the motor, with the power of which voltage has been converted to the target voltage.
