The decontamination method for fuel cell power plant 10 includes operating the device to generate power during an operating cycle, and then terminating operation of the device 10 during the decontamination cycle, and then Whenever the optimum electrical generation of the apparatus fuel cell 12 is reduced by at least 5% by the contaminants adsorbed by the fuel cell electrodes 24, 42, it is adsorbed by the electrodes 24, 42 of the fuel cell. Decontaminating the fuel cell 12 of the apparatus 10 during the contaminant removal cycle by oxidizing the contaminants. Oxidizing the contaminants may include exposing the electrodes 24, 42 to flowing oxygen, to heated flowing oxygen, to a series of start-stop cycles, and to varying controlled potentials. Can be achieved by n n Fuel Cell Power Unit, Contaminant Removal, Electrodes, Flow Oxygen, Potential |
