Platinum carbon black catalyst is a kind of electrochemical catalyst prepared by loading precious metal platinum on active carbon black (VXC72 or VXC72R). Platinum carbon black catalyst is mainly used in fuel cell hydrogen oxidation, methanol oxidation and oxygen reduction and other chemical reactions, is a very common precious metal catalyst. In the reaction process of fuel cells, PEMFC catalysts are also different according to the different electrodes, and anode catalysts are usually targeted at different fuels. Using electrocatalysts with high stability and high activity can achieve good catalytic effect on hydrogen oxidation
