Zusammenfassung:Disclosed herein are catalyst degradation detection assemblies and methods of catalyst degradation detection that can be performed in-situ. One embodiment of an in-situ fuel cell catalyst degradation detection assembly comprises a humidified hydrogen supply configured to supply humidified hydrogen to an anode of a fuel cell, a humidified nitrogen supply configured to supply humidified nitrogen to a cathode of the fuel cell, a collection cell containing a liquid, the collection cell configured to receive either cathode exhaust from the fuel cell through a cathode exhaust line or anode exhaust from the fuel cell through an anode exhaust line and means for detecting a gas.
