| 摘要 |
The invention relates to a method for operating equipment for producing hydrogen including at least one high-temperature electrolyzer for producing hydrogen, said electrolyzer comprising a plurality of basic cells, each of which comprises a cathode and an anode that are separated by an electrolyte, the basic cells being separated by an interconnection plate, each interconnection plate defining, with an adjacent cathode, a cathode compartment, and with an adjacent anode, an anode compartment, the cathodes being produced from a cermet containing nickel, said method comprising the steps: a) raising the temperature of the cells to an operating temperature of the electrolyzer of between 650°C and 950°C; and b) applying, to the terminals of the basic cells, a potential differential that is at least equal to 0.62 V. |
