摘要： A method for purging water from a fuel cell stack at fuel cell system shutdown. The method includes determining a stack water generation request to control the rate of drying of membranes in the stack and determining a cathode catalytic heating water generation request. A maximum charge a battery in the fuel cell system can accept is also determined. An ancillary power request for powering components of the fuel cell system during shutdown is determined. The method allocates how much of the water generation request will be fulfilled by operating the fuel cell stack to charge the battery and to provide the power needed for the ancillary power request, and how much of the water generation request will be fulfilled by cathode catalytic heating that produces water and heat in a cathode side of the fuel cell stack.

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 valve for a fuel cell system includes a valve housing having a valve seat formed therein. The valve seat includes an orifice 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 first end having an elongate portion and a generally conical shaped base. At least a portion of the base is disposed in the orifice of the valve seat when the movable member is in the closed position to militate against a formation of ice across the orifice of the valve seat.

摘要： A technique for reducing the amount of water that accumulates in an anode exhaust gas bleed line in a fuel cell system. The system includes a fuel cell stack, a cathode exhaust line and an anode exhaust line. The anode exhaust gas line is coupled to an anode bleed valve. An anode bleed line is coupled to the bleed valve and the cathode exhaust gas line so the hydrogen in the bled anode exhaust gas is diluted by the cathode exhaust gas. The anode bleed line is coupled to the cathode exhaust gas line so that a stand-off portion of the bleed line extends through a wall of the cathode exhaust gas line and into the cathode exhaust flow therein so as to prevent water and water vapor clinging to the inside surface of the cathode exhaust gas line from draining into the anode bleed line.
