60% platinum carbon black catalyst
60% platinum carbon black catalyst
CAS: 7440-06-4
Carrier: superconducting carbon black VXC72 or VXC72R
Appearance: black powder
Application scope：
It is mainly used in chemical reactions such as hydrogen oxidation of PEM fuel cells, hydrogen production by PEM electrolysis of water, methanol oxidation and oxygen reduction.
Principle of catalyst: Depending on the electrode, the fuel cell catalyst is also different. The anode catalyst is usually aimed at different fuels, and the electrocatalyst with high stability and high activity is usually platinum carbon black or platinum black catalyst. Cathode electrocatalysts mainly consider the issues of fuel permeation and oxygen reduction stability, so the choice of cathode electrocatalysts should be more cautious. The raw materials are fused by a solvent, metal precursors are added, the pH value is adjusted, etc., and a reducing agent is added at a specific temperature to obtain an electrocatalyst supported by metal platinum and carbon black.
