摘要： A method for determining when to operate a voltage recovery process for recovering a reversible voltage loss of a fuel cell stack in a fuel cell system. The method includes estimating an irreversible voltage loss of the fuel cell and an actual voltage of the fuel cell stack, and determining whether a difference between the estimated irreversible voltage loss and the estimated actual voltage exceed a threshold, and if so, the voltage recovery process is performed.

摘要： A hydrogen concentration sensor for measuring the hydrogen concentration in an anode sub-system of a fuel cell system. The hydrogen concentration sensor includes a membrane, a first catalyst layer on one side of the membrane and a second catalyst layer on an opposite side of the membrane where the sensor operates as a concentration cell. The first catalyst layer is exposed to fresh hydrogen for the anode side of a fuel cell stack and the second catalyst layer is exposed to an anode recirculation gas from an anode exhaust of the fuel cell stack. The voltage generated by the sensor allows the hydrogen partial pressure in the recirculation gas to be determined, from which the hydrogen concentration can be determined.

摘要： A method for determining a failure of a membrane in a fuel cell in a fuel cell stack. The method includes measuring the voltage of each fuel cell in the fuel cell stack, calculating an average cell voltage from all of the cell voltages of the fuel cells in the fuel cell stack, and identifying a minimum cell voltage from all of the cell voltages of the fuel cells in the fuel cell stack. The method then determines an absolute delta voltage value as the difference between the average cell voltage of the fuel cells and the minimum cell voltage of the fuel cells at a plurality of sample points during the sample period. A plurality of absolute delta voltage values determined over a plurality of sample periods, filtered for low current density are used to determine whether there is a membrane failure and, by filtering for high current density, to determine whether there is an electrode failure.

The method further includes calculating the catalyst surface area and the catalyst support surface area of the catalyst layers and comparing the difference between the identified catalyst surface area and the calculated catalyst surface area to estimate the change in the catalyst surface area.
