An industrial vehicle having a fuel cell system includes a vehicle key switch which has at least an ON position and an OFF position and is switchable between the ON position and the OFF position and a controller configured to control the fuel cell system in conjunction with manipulation of the key switch. When the controller detects that the key switch is turned from the OFF position to the ON position, the controller causes the fuel cell system to start electric power generation. When the controller detects that the key switch is turned from the ON position to the OFF position, the controller causes the fuel cell system to start a voltage maintenance control. When the controller detects that the key switch at the ON position is manipulated in a specified manner, the controller causes the fuel cell system to stop the electric power generation.
