Abstract: A method for opening tank shut-off valves in a fuel cell system that includes multiple pressurized tanks. A flow control device is positioned in a supply line downstream of the tank shut-off valves. When the system is started up, only one of the tank shut-off valves is opened to allow the pressure in the supply line to increase between the tank shut-off valves and the flow control device before the other tank shut-off valves are opened. Therefore, only one of the tank shut-off valves is subjected to the high pressure difference that induces significant valve wear and tear. The valve opening sequence is controlled so each of the tank shut-off valves is selected as the one to be opened at system start-up by a cycling process.

Abstract: A vehicle chassis with at least two fuel tanks with an engine engaged to the chassis structural member. Each of the fuel tanks has fuel level detector or sender. The level senders are engaged to an electronic controller. Each of the tanks has fuel draw line from it.

Activating the solenoid or control valve from closed to open, located in the draw side fuel line from the secondary tank, fuel is drawn from both tanks. The return goes only to the primary tank. When the levels are equalized, the electronic controller sends signal to the control valve to close.
