摘要： A method for determining whether a fuel cell stack is overheating. The method measures the temperature of end cells in the stack using end cell temperature sensors, and calculates an average end cell temperature based on the end cell temperature measurements. The method also measures the temperature of a cooling fluid being output from the fuel cell stack. The method determines if any of the measured end cell temperatures are outlying by comparing each end cell temperature measurement to the average. The method determines that the cooling fluid outlet temperature sensor has possibly failed if the cooling fluid outlet temperature is greater than the average end cell temperature and the cooling fluid outlet temperature minus the average end cell temperature is greater than a predetermined temperature value.

摘要： A fuel cell system that employs a method for increasing stack power ramp up for high power up-transients by decoupling the build-up of stack current density from the cathode side pressure. The system gives the compressor power priority during the power up-transient to quickly provide the proper compressor speed, and therefore the proper air mass flow, for the desired current density of the fuel cell stack. The system also maintains the cathode side pressure of the stack low by keeping a cathode back-pressure valve open. By increasing the cathode input airflow rate to the proper level at the power up-transient, the current density of the stack will increase to the desired stack power level. Subsequently, the back-pressure valve is closed to increase the stack voltage to provide the total maximum power achievable by the stack.

摘要： A system and method for limiting the amount of hydrogen being bled from an anode exhaust line. The method includes maintaining a pressure bias between an anode outlet and a cathode outlet of a fuel cell stack so that when an anode exhaust gas is bled from the anode exhaust line and mixed with the cathode exhaust gas, the concentration of hydrogen in the mixed gas is maintained below a predetermined percentage. The pressure bias is such that the anode exhaust gas has a higher gas pressure than the cathode exhaust gas.

摘要： A diagnostic method of detecting component failures in a fuel cell anode subsystem involves estimating fuel flow through injectors and comparing the estimated flow with a model based upon the system parameters. An observer based model is used to determine a residual value, the difference between the hydrogen input and the hydrogen consumed, and the residual is compared with a threshold range. In alternative embodiments, the stack current and the state of the valves are used to calculate the required hydrogen flow through the injectors and the duty cycle of an injector is compared to a tolerance range.
