Abstract: A system for determining the concentration of hydrogen in an anode sub-system of a fuel cell system. The fuel cell system includes at least one fuel cell, an anode inlet, an anode outlet, an anode recirculation line, a source of hydrogen gas and an injector for injecting the hydrogen gas. First and second acoustic sensors are provided in the anode recirculation line and are spaced a known distance from each other. A controller that is responsive to the output signals from the first and second acoustic sensors determines the concentration of hydrogen gas in the anode recirculation line based on the time between when the controller receives the sensor signal from the first sensor and receives the sensor signal from the second sensor.

Abstract: A system and method for controlling an injector in a fuel cell system. The method provides a variety of injector pulse widths for at least one predetermined duty cycle and determines an injector close time for each of the variety of injector pulse widths. The method also determines an error for the at least one predetermined duty cycle based on each of the provided injector pulse widths and uses the injector pulse width with the lowest error for the at least one predetermined duty cycle.

Abstract: A valve for a fuel cell system includes a valve housing having an inlet and an outlet formed therein. Each of the inlet and the outlet includes a passage formed therein to permit a fluid to flow through the valve housing. A movable member is disposed in the valve housing and is movable between an open position and a closed position. The movable member includes a sliding portion having a first flow regulator and a second flow regulator extending laterally outwardly therefrom. At least a portion of the first flow regulator is disposed in the passage of the inlet and at least a portion of the second flow regulator is disposed in the passage of the outlet when the movable member is in the closed position militating against a formation of ice across the entire opening of the inlet and the outlet.

Abstract: A system and method for detecting an intermittent failure of an injector that injects hydrogen gas fuel into the anode side of a fuel cell stack in a fuel cell system. The method includes operating the injector at a fixed injector pulse width and frequency, which causes the stack to generate a constant current, and therefore, a constant fuel consumption rate. While at a constant current, the injector is commanded to a constant duty cycle and frequency that matches the rate of fuel consumption in the fuel cell system. The resulting fuel pressure feedback is then monitored, and if it diverges from a defined nominal value, either in a constant or oscillatory manner, it can be determined that the injector has an intermittent opening failure. In one embodiment, the determination of the injector failure is performed during a shut-down sequence of the fuel cell system.
