SYSTEMS AND METHODS FOR MITIGATING CARBON CORROSION IN A FUEL CELL SYSTEM

摘要

System and methods for reducing carbon corrosion in a fuel cell system are presented. Particularly, the disclosed systems and methods may be utilized in connection with preventing the formation of a propagating H₂-Air interface within the fuel cell system. In certain embodiments, the disclosed systems and methods may utilize an electrochemical pump disposed in a cathode loop of the fuel cell system configured to remove oxygen that intrudes into the fuel cell system. In further embodiments, pumps may be included in an anode and a cathode loop of the fuel cell system that may allow for circulation of certain gases to prevent the formation of an H₂-Air front with the system.
