ABSTRACT:
A process for the production of hydrogen is disclosed. This process utilizes a photogalvanic effect of a polyacid ion and comprises immersing an anode into an aqueous solution of an alkylammonium salt of polytungstic acid or polyvanadic acid as an anode electrolyte, immersing a cathode into an aqueous solution of an acid as a cathode electrolyte, isolating both said aqueous solutions to each other, electrically connecting both said electrodes to each other, and irradiating a light onto said anode electrolyte, whereby hydrogen is evoluted at said cathode.
