<p>The invention relates to an electrode configuration of electrolysers using oxygen storage material to prevent oxidation of anodic active catalyst layer where oxygen storage material will be preferentially oxidised prior to anodic active catalyst. The inventions also relates to the use of hydrogen storage material with cathodic active catalyst to supply hydrogen to react with oxygen supplied from anodes when a reduction load is connected between the anode and cathode. One configuration utilises of individual layers containing oxygen and hydrogen storage materials, active catalyst layers, perforated current collectors, monopolar plates and a porous separator. A reduction load is used during operation of the electrolyser to convert metal oxides into pure metal by consuming oxygen from the electrolyser cell during stand by mode, shut down mode and intermittent operation, which will increase the durability of electrodes.</p> |
