Qinghua conquers hydrogen fuel cell catalyst mass production technology

Hydrogen fuel cells are increasingly used in new energy vehicles because of the advantages of "high efficiency, zero pollution". But the key materials that can make hydrogen fuel cells provide electricity, catalysts, China has always relied on high-cost imports. Recently, the research team of 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 driving is the first bus driven by China's fuel cell battery, which was successfully commissioned 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 internal combustion engines. The application of hydrogen fuel cells in developed countries in the West is accelerating because it has obvious advantages over pure electric vehicles.

The core materials and catalysts of hydrogen fuel cells have long been dependent on imports, resulting in high cost, which has restricted the independent development of China's hydrogen energy industry. In 2015, Tsinghua University jointly developed hydrogen fuel cell technology through school-enterprise cooperation. After more than two years, it finally overcomes the fuel cell catalyst mass production technology, as well as the technical upgrading and batch preparation of key components such as membrane electrodes and bipolar plates, and realizes the localization of key materials and components of hydrogen fuel cells. Similar products have been reduced by 50% to 80%, and some parts have exceeded the imported products.

At present, catalyst series products have been used in the fuel cell stacks of the Chinese Academy of Sciences, universities and many fuel cell companies. The fuel cell catalyst production line has been built, with a production capacity of 1200 g/day. It can meet the needs of 60 fuel cell buses and has large-scale industrial production conditions. It is expected that the production capacity of China's fuel cell reactors will reach more than 400,000 kilowatts this year.
