Abstract
Provided is a carbon catalyst for a cathode of a direct fuel cell, which selectively promotes an oxygen reduction reaction even when crossover of a fuel compound occurs. The carbon catalyst for a cathode of a direct fuel cell exhibits an oxygen-reducing catalytic activity in an electrolytic solution containing a fuel compound for the direct fuel cell, and exhibits substantially no catalytic activity to oxidize the fuel compound in the electrolytic solution.
