Abstract
Intercalation of metal chlorides into fine natural graphite flakes of 2 × 10−6 m in diameter was attempted. CuCl2 was satisfactorily intercalated from the vapour phase. NiCl2 and PdCl2 were also intercalated from the liquid phase using chloroform solvent. The reduction products of the obtained graphite intercalation compounds were used as carbon supports of the platinum electrocatalyst for a proton exchange membrane fuel cell. Oxygen reduction activity was evaluated and it can be seen that natural graphite flakes treated using the intercalation technique provide different levels of activity from that of pristine natural graphite flakes. In particular, the catalytic activity was enormously improved when CuCl2 was used as the intercalate.
