Summary
Electrocatalyst is the core material of proton exchange membrane fuel cell (PEMFC). The slow kinetics of anodic hydroxide reaction (HOR) and cathodic oxygen reduction reaction (ORR) is one of the main factors limiting the energy conversion efficiency, cost and stability of fuel cells. Platinum-carbon catalyst (Pt/C) is a carrier catalyst loaded with platinum on activated carbon to accelerate the energy conversion efficiency of PEMFC.

SEC series catalysts are self-developed products with self-hydrogen energy. They are mainly divided into the first generation of SEC101 platinum-carbon catalysts and the second generation of SEC201 low platinum catalysts with core-shell structure. The products of SEC series catalysts have the characteristics of small particle size and narrow particle size distribution, large electrochemical active area, low cost, high activity and high stability.
