Proton exchange membrane fuel cells have become a research hotspot in the field of new energy due to their high energy density, high energy conversion efficiency, low pollution, and low operating temperature. At present, in order to reduce the dependence of automobiles on gasoline, countries have invested in the research and development of new energy vehicle batteries. Among them, using hydrogen as fuel and truly realizing hydrogen fuel cell vehicles is recognized as one of the best solutions to solve today's transportation energy and environmental problems, and is the key to the key research of car companies in various countries.

     The key technology of hydrogen fuel cell "stuck neck" at present is the catalyst for hydrogen energy conversion. Previously, in order to develop hydrogen energy in our country, the required catalysts had to be imported from abroad, which restricted the development of hydrogen energy fuel cells in our country. Now our country urgently needs self-developed hydrogen fuel cell-related catalysts in order to solve the first hurdle of hydrogen energy from the source. Hydrogen fuel cell catalysts are related to the performance and life of fuel cells.

  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.
