Fuel cell catalyst is the core material in fuel cells, such as proton exchange membrane fuel cells (PEMFCs), which accelerates the electrochemical reaction rate (such as hydrogen oxidation and oxygen reduction), thereby improving the efficiency and power output of the cell.

SupportProduct Description
Fuel cell catalysts have the following core functions:;
Can reduce the activation energy of the reaction: accelerate the oxidation reaction of hydrogen (H ₂) at the anode (H ₂ → 2H ⁺+2e ⁻) and the reduction reaction of oxygen (O ₂) at the cathode (O ₂+4H ⁺+4e ⁻ → 2H ₂ O).
Improve electron transfer efficiency: reduce polarization loss, increase battery voltage and power density.
