  • Publication number: 20240167179
    Abstract: Carbon dioxide electrolysis apparatus includes: electrolysis stack having diaphragm including anion exchange type solid polymer electrolyte membrane and anode and cathode separated by diaphragm; carbon dioxide supply unit configured to supply carbon dioxide to gas flow path provided adjacent to cathode; power supply unit configured to supply electric power to stack; voltage sensor configured to detect stack voltage; temperature sensor configured to detect stack temperature; and control unit including processor and memory and configured to control power supply unit. Control unit controls power supply unit so that stack voltage becomes equal to or lower than upper limit value of stack voltage predetermined corresponding to stack temperature based on stack voltage detected by voltage sensor and stack temperature detected by temperature sensor during startup period until stack temperature reaches predetermined temperature after starting supply of electric power from power supply unit to stack.
