Abstract

The invention relates to the technical field of fuel cell catalysts, and specifically provides a fuel cell anode catalyst, a preparation method thereof and a proton exchange membrane fuel cell. The fuel cell anode catalyst is at least one of molybdenum carbide@hollow carbon sphere and platinum&molybdenum carbide@hollow carbon sphere, wherein the molybdenum carbide@hollow carbon sphere represents that the surface of the hollow carbon sphere is loaded with molybdenum carbide nanoparticles; and the platinum&molybdenum carbide@hollow carbon sphere represents that the surface of the hollow carbon sphere is loaded with molybdenum carbide nanoparticles and platinum nanoparticles at the same time. The anode catalyst is capable of improving the catalytic activity, carbon monoxide poisoning resistance and catalytic stability while reducing the loading amount of the platinum, and is beneficial for promoting the large-scale commercial application of the proton exchange membrane fuel cell.
