Hydrogen fuel cells are increasingly used in new energy vehicles because of the advantages of 'high efficiency, zero pollution'. But the catalysts that enable hydrogen fuel cells to supply electricity, China, have always relied on high-cost imports. Recently, Tsinghua University The university's research team conquered the industrialization of hydrogen fuel cell catalysts at a price that is only half that of similar imported products.
The bus that is driving is the first bus driven by China's fuel cell battery. It was successfully commissioned in Xianning, Hubei. Compared with traditional cars, its energy conversion efficiency is as high as 50% to 80%. It 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 material of hydrogen fuel cell - catalyst, long-term dependence on imports led to high cost, 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. After more than two years, finally It has overcome 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, realizing the localization of key materials and components of hydrogen fuel cells, and its cost is reduced by 50% compared with imported similar products. To 80%, the performance of some parts has exceeded the imported products.
At present, catalyst series products have been applied 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 capacity of 1200g/day, which can meet the needs of 60 fuel cell buses. And with large-scale industrial production conditions, it is expected that China's fuel cell reactor production capacity will reach 400,000 kilowatts this year.
