Good news! Sinocat undertakes the national key R&D projects of renewable energy and hydrogen energy technology during the 13th Five-Year Plan period
Since November 2020, Sinocat has undertaken a three-year national key R&D program - synthesis technology and batch fabrication of high-performance and anti-poisoning vehicle fuel cell catalyst. Actually, the company undertakes the 4th project - “R&D, organization and management of mass production of catalyst and verification of working condition” in this national key R&D project. The assessment specifications are as follows:
(1) Realize 2kg class for single batch production of catalyst. Set up a production line with capacity of more than 2000g/batch and more than 200kg/year.
(2) The performance of the catalyst will reach the final target:

Durability①0.6V~0.95V≥30000 cycles MA attenuation rate ≤40%, ECSA attenuation rate ≤40%
Durability②1.0V~1.5V≥ 5000 cycles MA attenuation rate ≤40%, ECSA attenuation rate ≤40%;
Mass activity degradation of volume production catalyst caused by CO is ≤ 30%（0.1 M HClO4 1000 ppm CO/H2, and performance degradation in MEA is ≤10mV（1 A/cm2，1 ppm CO/H2，24 h）
② The reduction of catalyst activity area caused by sulfide is ≤ 30% (0.36 ppm H2S, 24h), and performance degradation in MEA is ≤30 mV（1A/cm2，0.004 ppm H2S，24 h）

(4)Train 25 engineers, increase 65 jobs
SEC Series Catalysts
SEC series catalysts are self-developed products from Sinocat Hydrogen Energy, including the first generation platinum/carbon catalyst (SEC100) and the second generation core-shell structure platinum catalyst of low platinum content (SEC200). The synthesis process of SEC100 and SEC200 series catalysts is strictly and precisely controlled. The metal particles are evenly distributed on the carbon support and the precious metal content tolerance is ±1%.
