A porous gas-diffusion electrode having a ruthenium electrocatalyst is conditioned for operation as a hydrogen consuming anode by connecting the electrode as a cathode in a suitable electrolyte until it drops below the reversible hydrogen potential and evolves hydrogen. Preferably, the electrode is contacted with a hydrogen atmosphere prior to or at the beginning of hydrogen evolution, and conditioning may be carried out in situ in a cell in which the electrode is to operate as hydrogen consuming anode. |
