<p>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.</p> |
