Abstract: An object is to provide a methane synthesis device having as a whole a reduced size and a simplified configuration. A methane synthesis device 100 is composed of respective components from an end plate 2 at the leftmost side to an end plate 23 at the rightmost side and is compactly assembled by fastening plural bolts and nuts to bring these individual components into tightly contact with each other. The components may be divided into a Sabatier reaction unit of signs 3 to 9, a water electrolysis unit of signs 13 to 19, and other components. Hydrogen gas generated in the water electrolysis unit is mixed with carbon dioxide gas and supplied to the Sabatier reaction unit, and methane is synthesized in the Sabatier reaction unit. The size of the device is reduced as a whole and configuration is simplified by integrally stacking the water electrolysis unit, the Sabatier reaction unit, a carbon dioxide supplying unit, and a hydrogen gas supplying unit.

Abstract: Provided are a water electrolysis method and a water electrolysis device in which mixing of the generated hydrogen and oxygen is greatly reduced and which have a high electrolysis efficiency, while being simplified in structure. In the water electrolysis method and water electrolysis device, water is electrolyzed by supplying water to the cathode side of an electrolytic membrane including a solid polymer membrane provided with a catalyst layer on a surface thereof and creating a potential difference between both surfaces of the electrolytic membrane. The temperature-controlled water is supplied only to the cathode side of the electrolytic membrane, while controlling the difference in pressure between both surfaces of the electrolytic membrane to 50 kPa or less.
