Abstract

The present invention discloses a method of producing hydrogen halide and oxygen by reacting water and halogen as represented by the following formula: EQU H.sub.2 O+X.sub.2 .fwdarw.HX+1/2O.sub.2 ( 1) (wherein, X represents a halogen), wherein activated carbon is used as catalyst, said activated carbon is inserted into an aqueous solution containing said halogen as an electrode, a counter electrode is inserted into said solution and, after bringing this counter electrode into contact with said active carbon electrode, the above reaction takes place in a reaction system in which said activated carbon electrode and counter electrode are connected outside said aqueous solution. Moreover, a voltage is applied between the activated carbon electrode and counter electrode, and contact between the activated carbon electrode and counter electrode is made through an anion electrolyte membrane. In addition, openings are provided in this anion electrolyte membrane.
