摘要： Disclosed herein are processes for recovering performance of fuel cells by recovering fuel cell catalyst activity and methods of testing the durability and activity performance of fuel cells. One catalyst recovery process disclosed herein for a fuel cell having a membrane electrode assembly comprises operating the fuel cell for a first recovery cycle with fuel gas supplied to an anode of the fuel cell and an oxidant supplied to a cathode of the fuel cell while drawing a current from the fuel cell at steady state throughout the first recovery cycle, the first recovery cycle having a predetermined time period. The fuel cell has reached end of life due in part to intermittent use prior to operating the fuel cell for the first recovery cycle. A life of the fuel cell improves when the first recovery cycle is complete.
