Disclosed is a low-cost high-performance catalyst for a direct liquid fuel cell, which is capable of suppressing decrease in the cathode potential due to crossover of liquid fuel in a direct liquid fuel cell wherein liquid fuel such as methanol, ethanol, formic acid, 2-propanol or dimethyl ether is directly supplied. The catalyst for a direct liquid fuel cell is characterized by being composed of a metal oxycarbonitride that contains niobium and/or titanium. It is preferable that the catalyst for a direct liquid fuel cell is inert to oxidation of the liquid fuel. |
