Because of the advantages of "high efficiency and zero pollution", hydrogen fuel cells are increasingly used in new energy vehicles. However, China has always relied on high cost imports of catalysts, which are the key materials for hydrogen fuel cells to provide electricity. Recently, the research team of Tsinghua University solved the problem of industrialization of hydrogen fuel cell catalyst, and the price is only half of that of similar imported products.

The bus in motion is the first bus driven by fuel cells made in China, which has been successfully tested in Xianning, Hubei Province. Compared with traditional cars, its energy conversion efficiency is as high as 50% to 80%, which is 2 to 3 times that of internal combustion engines. The application of hydrogen fuel cell in western developed countries is speeding up, because it has obvious advantages over pure electric vehicles.

Catalyst, the core material of hydrogen fuel cell, has long relied on imports, leading to high costs, which restricts the independent development of China'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 overcome the mass production technology of fuel cell catalyst, as well as the technical upgrading and batch preparation of key components such as membrane electrodes and bipolar plates, and realized the localization of key materials and parts of hydrogen fuel cells. Its cost was 50% to 80% lower than that of similar imported products, and the performance indicators of some parts have exceeded that of imported products.

At present, catalyst series products have been used in fuel cell stacks of Chinese Academy of Sciences, universities and many fuel cell companies. The mass production line of fuel cell catalyst has been built, with a capacity of 1200g/day, which can meet the requirements of 60 fuel cell buses and has the conditions for large-scale industrial production. It is estimated that the production capacity of fuel cell stacks in China will reach 400000 kilowatts this year.
