Abstract
Disclosed herein are systems and methods for recovering performance of fuel cells by recovering fuel cell catalyst activity. One system for recovering catalyst performance of a fuel cell stack made of one or more fuel cells in a vehicle comprises a sensor for detecting an EOL state of the fuel cell. A notification device notifies a user when the sensor detects the EOL state of the fuel cell. Means for drawing a steady-state load from the fuel cell stack is used to operate the fuel cell stack until the catalyst performance is recovered.
