Abstract
A method for operating an installation for producing hydrogen including at least one high temperature electrolyzer for producing hydrogen, the electrolyzer including a plurality of elementary cells, each including a cathode and an anode separated by an electrolyte, the elementary 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 made from a cermet containing nickel, the method including: a) raising a temperature of the cells up to an operating temperature of the electrolyzer comprised between 650° C. and 950° C.; b) applying a potential difference on terminals of the elementary cells at least equal to 0.62 V.
