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 carrier, the dispersion of the active metal 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, for the anode and cathode catalysts of PEM fuel cells, Pt series catalysts or ruthenium catalysts can be selected. 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-metal 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.
