Gas phase electrolysis of HBr or HI was studied by using a fuel-cell-type electrolyzer provided with graphite gas diffusion electrodes and liquid film electrolyte of H<SUB>3</SUB>PO<SUB>4</SUB>. Current efficiency 100% may be achieved at decomposition voltages of 0.73 V (at 100 mA cm<SUP>−2</SUP> and 150 °C) for HBr and 0.28 V (at 100 mA cm<SUP>−2</SUP> and 145 °C) for HI. Both bromine and iodine produced may smoothly be evolved out of the anode in the gas or liquid form without being dissolved into the electrolyte H<SUB>3</SUB>PO<SUB>4</SUB>, causing no trouble on the separation of products. This electrolytic method may be incorporated in the bromine or iodine cycles for thermochemical hydrogen production to constitute an effective hybrid system.
