摘要
Process for prodn. of hydrogen comprises passing an electric current through an aq. electrolyte between an anode and a hydrogen evolution cathode consisting of a monolithic structure with a surface formed from an integral precursory, adherent Raney Beta phase ternary alloy (Ni)x(Mo)yA13 in which x=80-95%, y=20-5% and x+y=100%, and which has had 75-95% of the aluminium leached from the surface with a strong aq. base so as to form an active porous Raney Beta phase Ni-Mo surface layer so that the hydrogen overvoltage of the surface is reduced. The cell may be divided into anode and cathode compartments by means of a membrane made from a perfluorinated polymer having lateral side chains chosen from carboxylic acid and sulphonic acid functional gps. The cathode have a low overvoltage for use as a hydrogen evolution cathode in an electrolytic cell.
