(2) The catalyst performance completely reaches the final index:

The initial ORR MA≥0.4A/mgPt@0.9VIR-free, ECSA≥ 60m2/g;

Durability ①0.6V~0.95V≥ 30,000 cycles MA decay rate ≤40%, ECSA decay rate ≤40%,

Durability of 1.0V~1.5V≥ 5000 cycles MA decay rate ≤40%, ECSA decay rate ≤40%;

Resistance to poisoning:

The mass activity of the mass production catalyst decreased by less than 30% (0.1 M HClO4 1000 PPM CO/H2); ② the decrease of active area of mass production catalyst caused by sulfide is less than 30% (0.36 PPM H2S, 24h);

Particle size and performance deviation ≤ ±8%, Cl- content less than 50 PPM wt, Fe content less than 50 PPM wt.

SEC series catalyst

SEC series catalysts are self-developed products of hydrogen energy, including the first generation of SEC100 platinum carbon catalyst and the second generation of SEC200 low platinum catalyst with core-shell structure. The SYNTHESIS PROCESS of SEC SERIES CATALYSTS HAS strict and precise control, the metal particles are evenly distributed on the carbon support, and the noble metal content tolerance is less than or equal to SH1%.
