Abstract

A liquid material comprising hydrogen and oxygen is produced by electrolyzing an electrolysis solution containing 5 to 30% by weight of an electrolyte in an electrolysis tank using a group of electrodes disposed, within the electrolysis tank, while maintaining a spacing of 3 to 10 mm between adjacent electrodes under conditions of a current density of 5 to 20 A/dm 2 , a bath temperature of 20 to 70° C., and pH 14 or more (strongly alkaline) while applying vibration stirring, bringing the pressure of the resultant gas comprising hydrogen and oxygen to 0.1 to 0.5 MPa, and cooling the gas to −190 to −250° C. to liquefy the gas. The liquid material is stored, is returned to room temperature, and is gasified to produce a regasified gas comprising hydrogen and oxygen.
