摘要： A method for determining the flow of an anode gas out of an anode sub-system. The method includes providing pressure measurements at predetermined sample times over a predetermined sample period and using the pressure measurements to calculate a slope of a line defining a change of the pressure from the beginning of the time period to the end of the time period. The slope of the pressure line is then used in a flow equation to determine the amount of gas that flows out of the anode sub-system, which can be through a valve or by system leaks.

摘要： A system and method for preventing anode reactant starvation. The system includes a hydrogen source, an anode bleed valve, and a cell voltage monitor. The system also includes an anode sub-system pressure sensor and a controller configured to control the anode sub-system. The controller determines the average cell voltage and estimates the hydrogen molar fraction and/or nitrogen molar fraction in the anode sub-system. The controller also receives measurement data from the cell voltage monitor and the pressure sensor, and determines whether there is a decrease in the minimum cell voltage in response to changes in the anode pressure. If the controller detects a decrease in the minimum cell voltage in response to changes in the anode pressure, the controller corrects for the decrease by increasing anode pressure and/or by decreasing the molar fraction of nitrogen in the anode sub-system.

摘要： A system and method for determining whether an anode injector that injects hydrogen gas into an anode side of a fuel cell stack has failed. The method includes monitoring a voltage of the fuel cell stack and performing spectral analysis of the stack voltage to identify amplitude peaks in the stack voltage. The method further includes determining whether the spectral analysis of the stack voltage has identified an amplitude peak at a location where an amplitude peak should occur if the injector is operating properly. If no amplitude peak is identified at that location, then the method determines that the injector is not operating properly. If an amplitude peak is identified at that location, then the method compares the amplitude peak to the desired amplitude peak to identify if it is within a threshold to determine if the injector is operating properly.

摘要： A system and method for correcting an estimation of nitrogen in an anode side of a fuel cell stack. The system includes a fuel cell stack and a pressure sensor for measuring pressure in an anode sub-system. The system also includes a controller configured to control the estimation of nitrogen permeation from the cathode side to the anode side of the stack, where the controller determines if the pressure in the anode sub-system equilibrates with atmospheric pressure in a shorter period of time after shutdown compared to the time necessary for the anode sub-system to reach approximately atmospheric pressure after a previous shutdown or calibrated time value, and corrects the estimation of nitrogen in the anode side of the stack if the pressure equilibrates in a shorter period of time.

摘要： A system and method for controlling hydrogen gas flow to an anode side of a fuel cell stack using a pressure regulator in the event that an injector that normally injects the hydrogen gas into the fuel cell stack has failed in a stuck open position. During normal operation, the control of the injector is determined based on the pressure of an anode sub-system and the position of the pressure regulator is determined based on a supply pressure between the pressure regulator and the injector. If it is determined that the injector is stuck in an open position, then the position of the pressure regulator is controlled to the anode pressure instead of the supply pressure. If the pressure regulator is an electrical pressure regulator, then it is pulsed to mimic normal system operation. Alternately, another valve, such as a shut-off valve, can be employed to provide the flow pulsing.

摘要： 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.

摘要： A method for determining the amount of fuel flow from a high pressure gas tank to the anode side of a fuel cell stack through pulsed injector. The anode sub-system pressure is measured just before the injector pulse and just after injector pulse and a difference between the pressures is determined. The difference between the pressures, the volume of the anode sub-system, the ideal gas constant, the anode sub-system temperature, the fuel consumed from the reaction in the fuel cell stack during the injection event and the fuel cross-over through membranes in the fuel cells of the fuel cell stack are used to determine the amount of hydrogen gas injected by the injector.

摘要： A system and method for detecting an anode pressure sensor failure in a fuel cell system. The system and method include a controller that sets an initial minimum anode pressure sensor value and an initial maximum anode pressure sensor value. The controller determines a desired time interval for sampling anode pressure measurements and determines a total number of samples of anode pressure measurements to be collected by the controller from an anode pressure sensor. The controller also compares a pressure difference between the initial or a measured minimum anode pressure and the initial or a measured maximum anode pressure to a predetermined pressure difference threshold and sets a pressure sensor fault if the pressure difference between the initial or measured minimum anode pressure and the initial or maximum anode pressure is less than the predetermined pressure difference threshold.
