| Research Abstract |
A novel electrochemical oxygen separation process using a hydroxide ion conductor as an electrolyte has been proposed. In this study, we used Ni-Fe layered double hydroxide (LDH) intercalated with carbonate anion as a hydroxide ion conductive material. The electrodes using Pt/C as a catalyst were prepared, and a membrane reactor for oxygen separation using Ni-Fe LDH as an electrolyte was fabricated. The electrochemical oxygen product flow was confirmed to be proportional to the external current density at 50 degree C under 70% of relative humidity, indicating that electrochemical oxygen separation using Ni-Fe LDH as hydroxide ion conductive material was functioned.
