Abstract
The invention is a start up system and method for a fuel cell power plant () using a purging of the cathode flow field () with a hydrogen rich reducing fluid fuel to minimize corrosion of the cathode electrode (). The method for starting up the shut down fuel cell power plant () includes the steps of: a. purging the cathode flow field () with the reducing fluid fuel; b. then, directing the reducing fluid fuel to flow through an anode flow field (); c. next, terminating flow of the fuel through the cathode flow field () and directing an oxygen containing oxidant to flow through the cathode flow field (); and, d. finally, connecting a primary load () to the fuel cell () so that electrical current flows from the fuel cell () to the primary load ().
