ABSTRACT:
The anodes of fuel cells in a fuel cell stack are passivated during no load, hot-hold periods by directing a stream of desulfurized natural gas through the anode side of the cells in the stack. The cell voltage is thus maintained below 800 millivolts, preferably between 300 and 500 millivolts, during such periods.
