Shaanxi Kaida Chemical Co., Ltd. specializes in the research and development and production of precious metal catalysts. The large-scale preparation technology is mature, and it provides key precious metal catalysts for many domestic professional manufacturers of PEM fuel cells and electrolytic water hydrogen production. Through carrier screening, changing the structure and properties of the support, the dispersion of active metals, and the improvement of the preparation process conditions, the precious metal catalysts with high activity, high stability and long life can be produced. At present, due to the harsh conditions of use, the anode catalysts for PEM electrolytic water hydrogen production can usually only use Ir series catalysts, and the cathode catalysts mainly choose Pt series catalysts; for PEM fuel cells, the anode and cathode catalysts can choose Pt series catalysts. Through more than 20 years of systematic research, Kaida has deeply understood the effects of factors such as pH value, amount of protective agent, and reduction conditions in the catalyst preparation system on the performance of nano-Ir and Pt series catalysts, and has achieved large-scale production of PEM fuel cells and electrolytic water to produce hydrogen cathode and anode precious metal catalysts through relevant measures.
