Title: METHODS AND SYSTEMS FOR HYDROGEN GAS PRODUCTION THROUGH WATER ELECTROLYSIS, AND RELATED ELECTROLYSIS CELLS
Abstract:
A method of producing hydrogen gas comprises introducing gaseous water to an electrolysis cell comprising a positive electrode, a negative electrode, and a proton conducting membrane between the positive electrode and the negative electrode. The proton conducting membrane comprises an electrolyte material having an ionic conductivity greater than or equal to about 10-2 S/cm at one or more temperatures within a range of from about 150°C to about 650°C. The gaseous water is decomposed using the electrolysis cell. A hydrogen gas production system and an electrolysis cell are also described.
