Official abstract text for this publication.
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.
Opening claim text (preview).
What is claimed is: 1 . An industrial vehicle having a fuel cell system, comprising: a key switch having at least an ON position and an OFF position and 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, wherein 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, and 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. 2 . The industrial vehicle having the fuel cell system according to claim 1 , wherein when a specified period of time has elapsed since the start of the voltage maintenance control, the controller causes the fuel cell system to stop the electric power generation. 3 . The industrial vehicle having the fuel cell system according to claim 1 , wherein when the controller detects that the key switch at the ON position is manipulated to be cycled from the ON position to the OFF position successively a specified number of times, the controller causes the fuel cell system to stop the electric power generation. 4 . The industrial vehicle having the fuel cell system according to claim 1 , wherein the key switch further has a STARTER position, and when the controller detects that the key switch at the ON position is manipulated to be turned from the ON position to the STARTER position and then to the OFF position, the controller causes the fuel cell system to stop the electric power generation.
