Abstract
Systems and methods for measuring in-situ membrane fluid crossover are provided. One embodiment of a system for diagnosing in situ degradation of membranes in a fuel cell stack comprises an inert gas supply configured to be connected to the fuel cell stack to supply an inert gas to an anode side of the fuel cell stack during diagnosis and an analyzer, for example, for detecting an amount of crossover cathode gas in exhaust from the anode side of the fuel cell stack during diagnosis.
