摘要： A power supply apparatus has a combined power source with power cells configured electrically independently. A switch arbitrarily changes connection paths of the power cells by selectively connecting power cell terminals through switching elements. A voltage detector detects differences in electrical potentials between the power cell terminals. A controller controls ON-OFF states of the switching elements by controlling the switch by a control signal generated based on voltage signals representing the differences in electrical potentials detected by the voltage detector so as to isolate one of the power cells to stop a supply of electric power therefrom when a voltage generated in the power cell has dropped to a specified voltage or lower. The controller restarts the supply of electric power from the power cell whose power supply has been stopped when the duration of a down time of the power cell has reached a predetermined time or longer.

摘要： Disclosed is a method for detecting ice blocking of a fuel cell stack. In particular, the method includes periodically calculating a minimum cell voltage of a fuel cell stack from cell voltages measured by a cell voltage monitoring system while reactant gases are supplied to the fuel cell stack and then calculating a change in the minimum cell voltage using a currently calculated minimum cell voltage and a previous minimum cell voltage. It is then determined whether the change in the minimum cell voltage is above a predetermined reference value. When the change in the minimum cell voltage is above the reference value, it is determined that the ice blocking has occurred or is occurring in an anode of the fuel cell stack.

摘要： A system and method for detecting and predicting low performing cells in a fuel cell stack. When the fuel cell stack is running and certain data validity criteria have been met, an algorithm collects the data, such as stack current density, average cell voltage and minimum cell voltage. This information is used to estimate predetermined parameters that define the stack polarization curve. The system defines a predetermined minimum current density that is used to identify a low performing cell. The system then calculates an average cell voltage and a minimum cell voltage at the minimum current density set-point, and calculates a cell voltage difference between the two. If the cell voltage difference is greater than a predetermined low voltage threshold and the minimum cell voltage is less than a predetermined high voltage threshold, the algorithm sets a flag identifying a potential for a low performing cell.

摘要： A method for determining a low performing cell in a fuel cell stack. The method measures the voltage of each cell in the fuel cell stack and calculates an average cell voltage of all of the cell voltages from the fuel cell stack at a plurality of stack current densities. The method also identifies a minimum cell voltage from all of the cell voltages from the fuel cell stack at the plurality of stack current densities that the average cell voltages are calculated and determines a relative delta voltage relationship between the average cell voltage and the minimum cell voltage at each of the plurality of stack current densities. The relative delta voltage relationships are used to determine whether the minimum cell voltage indicates a persistent stack problem.

摘要： An isolation fault detection system for detecting isolation faults in a fuel cell system associated with a fuel cell hybrid vehicle. The isolation fault detection system measures a stack voltage potential, a positive fuel cell voltage potential, a negative fuel cell voltage potential, a positive battery voltage potential, and an overall battery voltage potential. The isolation fault detection system then uses these voltage potentials in mesh equations to compare the measured voltage potentials to voltage potentials that would occur during a loss of isolation. In one embodiment, the isolation fault detection system uses these five measured voltage potentials to determine whether an isolation fault has occurred at four separate locations in the fuel cell hybrid vehicle. The system also can detect the location of the isolation fault.

摘要： There is provided an impedance measuring system which can accurately measure the impedance of a fuel cell. A motor rotation number detection unit successively detects the rotation number of a motor controlled by an inverter and outputs the detection result to a superposition signal generation unit The superposition signal generation unit sets the frequency of an impedance measuring signal to a non-resonant frequency so that the control signal of the motor not resonate with the impedance measuring signal. Thus, by setting the frequency of the impedance measuring signal to the non-resonant frequency, the resonance with the motor is suppressed, which can improve impedance measurement accuracy.
