Hydrogen fuel cells are increasingly used in new energy vehicles due to their advantages of "high efficiency and zero pollution". But my country has always relied on high-cost imports of catalysts, the key material that enables hydrogen fuel cells to provide electrical energy. Recently, a research team from Tsinghua University has overcome the industrialization problem of hydrogen fuel cell catalysts, and the price is only half of that of similar imported products.

　　The bus that is running is my country's first bus powered by fuel cells made of domestically produced materials. It was successfully trial-run in Xianning, Hubei. Compared with traditional cars, its energy conversion efficiency is as high as 50% to 80%, which is 2 to 3 times that of an internal combustion engine. The application of hydrogen fuel cells in Western developed countries is accelerating because it has obvious advantages compared with pure electric vehicles.

　　Catalysts, the core material of hydrogen fuel cells, have long relied on imports, resulting in high costs and restricting the independent development of my country's hydrogen energy industry. In 2015, Tsinghua University jointly developed hydrogen fuel cell technology through school-enterprise cooperation. It took more than two years to finally conquer the mass production technology of fuel cell catalysts, as well as the technical upgrade and batch preparation of key components such as membrane electrodes and bipolar plates, and realize the localization of key materials and components of hydrogen fuel cells at a lower cost than imported ones. Similar products have dropped by 50% to 80%, and the performance indicators of some parts have exceeded imported products.
