    摘要： A method for monitoring the pressure in an anode sub-system of a fuel cell system during a pressurization stage at system start-up prior to an anode purge. The method includes providing hydrogen gas to the anode sub-system during the pressurization stage, typically from one or more injectors. The method determines how many moles of the hydrogen gas has been provided to the anode sub-system, and uses the number of moles to determine the pressure in the anode sub-system. The method uses the determined pressure to stop the pressurization stage when the determined pressure is about equal to the desired pressure.

    摘要： A system and method for determining whether valves in a fuel cell system bleed manifold unit (BMU) are blocked with ice or have otherwise failed. The system opens a first bleed valve, closes a second bleed valve and opens an exhaust valve, and then reads a pressure signal to determine whether there is flow through a flow restriction to determine whether the first bleed valve or the exhaust valve is blocked. The system then closes the exhaust valve, leaves the first bleed valve open, and again reads the pressure signal to determine the pressure drop across the flow restriction, which will indicate whether the flow restriction the pressure sensor lines are blocked. The system then closes the first bleed valve and opens the second bleed valve to determine whether the pressure signal indicates a flow through the second bleed valve.
