Abstract
Aspects of methods and systems to reduce degradation of a fuel cell () during start-up and shut-down cycles are disclosed. An anode exhaust stream (') is periodically directed via fluid communication through an oxygen capture media (). After shut-down of the fuel cell and before or during start-up said media () removes oxygen in the anode exhaust stream. Periodically, heating the oxygen capture media () is employed to purge the oxygen collected and regenerate the media.
