Zusammenfassung:Disclosed herein are systems and methods of diagnosing in situ the health of a fuel cell stack while it is in operation in a vehicle. One such system of diagnosing in situ the health of a fuel cell stack while it is in operation in a vehicle comprises at least one gas sensor configured to detect a gas in exhaust from the fuel cell stack and a control unit configured to receive data from the gas sensor. The control unit has baseline data particular to a catalyst of the fuel cell stack and is programmed to determine information from the baseline data and the data from the gas sensor, the information providing a condition of the fuel cell stack. A display unit is configured to display an indication of the condition.
