Break the monopoly, hydrogen fuel cell catalyst to achieve mass production

The reporter learned from the new energy and materials chemistry Research Office of Tsinghua University's Institute ofspecial and new energy technology that the industrialization of catalyst production of key fuel cell materials has been overcome by the joint research and development team of the hydrogen fuel cell laboratory of Tsinghua University and a technology company in Wuhan. At present, the catalyst has 17 patents, with a capacity of 1200 grams per day, and the price is only half that of imported products.

Catalyst as the core material of fuel cell, its comprehensive performance and localization are directly related to the core competitiveness of fuel cell technology in China and its industrialization prospects. However, the related intellectual property rights have always been in the hands of a few developed countries in the West. The high cost of the catalyst core materials has long relied on imports, which has restricted the independent development of China's hydrogen energy industry.

In 2015, Tsinghua University and Wuhan Himalaya Optoelectronics Technology Co., Ltd. carried out in-depth cooperation between the school and enterprises, and jointly used the catalyst preparation process of Tsinghua University to carry out the mass production technology of the Pt/C catalyst. At present, the catalyst production capacity has reached 1200 g/day, which can meet the needs of 40 36kW fuel cell electric reactors and have large-scale industrial production conditions. This series of results completely broke the long-standing monopoly of the technology in a few countries, and the price is only half that of similar imports.

Catalyst serialization products have been applied to fuel cell reactors of the Chinese Academy of Sciences, universities and several fuel cell companies. At the end of this year, up to 1,000 hydrogen fuel cells will be produced using the catalyst.

The next step will be to improve the catalyst's parameters, to increase the tolerance of sulfides, nitrides and other impurities, and to inject strong power into the domestic production of fuel cells in China, said Wangcheng, the leader of the attack team and director of the hydrogen fuel cell laboratory at Tsinghua University.
