摘要： A fuel cell system that increases stack stability by reducing the amount of liquid water droplets at the anode input of a fuel cell stack in the system. Re-circulated anode exhaust gas from the fuel cell stack and fresh hydrogen gas are sent to an anode heat exchanger so that both the fresh hydrogen gas and the re-circulated anode exhaust gas are heated to reduce the formation of water droplets in the anode input gas. Further, a portion of the heated cooling fluid directly from the fuel cell stack is sent to the heat exchanger to heat the fresh hydrogen gas and the re-circulation hydrogen before the cooling fluid is sent to an isolation heat exchanger to have its temperature reduced.

摘要： A system and method for putting a fuel cell system in a stand-by during a system idle condition to improve system fuel efficiency. The method can include diverting the cathode airflow around the stack, reducing an airflow output from a cathode compressor to a minimum allowable set-point, opening the stack contactors to disconnect the stack from the high voltage bus and electrically isolate the stack from the rest of the system, engaging an independent load to the stack, such as end cell heaters in the stack, to suppress stack voltage, maintaining a positive pressure in the anode side of the fuel cell stack and periodically bleeding the anode into the exhaust stream. When a system power request is made removing the idle condition, the system returns to normal operation by directing the airflow back to the cathode and opening the stack contactors when an open circuit voltage is attained.

摘要： A system and method for quickly heating a fuel cell stack at fuel cell system start-up. The fuel cell system includes a three-way valve positioned in the anode exhaust that selectively directs the anode exhaust gases to the cathode input of the fuel cell stack so that hydrogen in the anode exhaust gas can be used to heat the fuel cell stack. During normal operation when the fuel cell stack is at the desired temperature, the three-way valve in the anode exhaust can be used to bleed nitrogen to the cathode exhaust.

摘要： A system for bleeding the anode side of first and second split fuel cell stacks in a fuel cell system that employs anode flow-shifting, where each split stack includes a bleed valve. The system determines that one or both of the bleed valves is stuck in an open position if there is flow through an orifice and a bleed has not been commanded. A shut-off valve is then used to provide the bleed if the cathode exhaust gas is able to dilute the hydrogen in the bled anode exhaust gas. An outlet valve between the first and second split stacks is used to bleed the anode exhaust gas if the cathode exhaust gas is not significant enough to dilute the hydrogen in the anode exhaust gas. If the first or second bleed valve is stuck in the closed position, then the outlet valve is used to provide the bleed.

摘要： A method for performing a plausibility check of a fuel cell stack anode side pressure sensor to determine whether the pressure sensor is providing an accurate measurement. Prior to system start-up when a cathode side compressor is not providing cathode air to a fuel cell stack, and the cathode side of the stack is at ambient pressure, a pressure measurement from a differential pressure sensor between the anode side and the cathode side of the fuel cell stack is provided. The differential pressure sensor reading is added to a pressure measurement from an ambient pressure sensor, where the sum should be about the same as the pressure measurement from the anode side pressure sensor if the anode side pressure sensor is operating properly.

摘要： A method is provided for controlling the concentration of nitrogen in a fuel cell stack. The method includes providing a fuel cell stack with cathode passages and anode passages including a valve in communication with the anode passages. The method further comprises selecting a maximum desired amount of nitrogen to be found in the fuel cell stack and calculating an actual amount of nitrogen in the fuel cell stack. Next, the method provides for comparing the maximum desired amount of nitrogen in the fuel cell stack to the actual amount of nitrogen in the fuel cell stack, and opening the valve if the actual amount of nitrogen in the fuel cell stack is greater than the maximum desired amount of nitrogen in the fuel cell stack. The method calculates the actual amount of nitrogen in the fuel cell stack based on an amount of nitrogen that enters the anode passages due to an age of the fuel cell stack.
