Abstract: A solid electrolyte is composed primarily of a component expressed by a composition formula of Li a+d M b X c A e O f by using values a to f that are greater than 0, where M is an element serving as a trivalent cation, X is a halogen element, and A is a sulfur element or a phosphorus element, wherein 0.8c ≤ (a + 3b) ≤ 1.2c and 1.6f ≤ (d + n × e) ≤ 2.4f are satisfied, where when A is a sulfur element, n is 4 or 6, and when A is a phosphorus element, n is 5. Accordingly, it is possible to provide a solid electrolyte having high lithium ion conductivity and high-temperature stability.

Abstract: A methane production system (1) includes a co-electrolysis/reforming cell (32) and a control unit (60) that controls the operating temperature of the co-electrolysis/reforming cell (32). The co-electrolysis/reforming cell (32) operates in either a co-electrolysis mode in which H 2 and CO are produced at a first electrode (2) from COz and HzO, or a reforming mode in which CH 4 is produced at the first electrode (2) from the H 2 and CO produced in the co-electrolysis mode. The control unit (60) makes the operating temperature of the co-electrolysis/reforming cell (32) in the reforming mode lower than the operating temperature of the co-electrolysis/reforming cell (32) in the co-electrolysis mode.
