PROBLEM TO BE SOLVED: To provide a carbon-based electrode material for an electrolytic cell having an enhanced energy efficiency by suppressing a detrimental side reaction improving current efficiency and by reducing a cell resistance and hence improving voltage efficiency. SOLUTION: This carbon-based electrode material for an electrolytic cell consists of a carbon material having a pseudo-graphite crystal structure with spacing between the <002> planes obtained by X-ray wide angle analysis <=3.70 Å and a BET surface area >=5 m<2> /g. The number of bonded nitrogen atoms to the surface of the carbon material is set >=0.3% in relation to the number of carbon atoms, and the nitrogen atoms bonded to the surface are made to exist in the form of a nitrogen-containing acidic functional group. |
