PURPOSE:To provide a carbon electrode for an electrolytic cell having long cycle life, with which exceedingly high cell energy efficiency can be got. CONSTITUTION:A carbonaceous material provided by carbonizing polyacrylonitrile fiber as it has pseudo-graphitic crystal structure and has <002> spacing of not less than 3.50Angstrom and not more than 3.60Angstrom in X-ray wide angle analysis, and after that, treated through air oxidation as the atomic weight of bond oxigen in the surface of the carbonaceous material accounts for 10-25% of the atomic weight of carbon, is used as electrodes 5 for an electrolytic cell. In this way, an electrode, which is superior in the electrochemical reaction selectivity and the electrode activity, can be provided, and an electrolytic cell having such electrodes can be made to have high cell energy efficiency and long cycle life. |
