"Nature · Communication" recently published the latest research results of Wuhan University on alkaline polymer electrolyte fuel cell non-precious metal catalysts, revealing an important principle of fuel cell catalyst design, is expected to significantly reduce the cost of fuel cells, and solve China's current vehicle fuel The key material of battery depends on import.
The reporter learned from Wuhan University on the 19th that the research team of Zhuang Lin and Xiao Li of the School of Chemistry and Molecular Science combined a variety of spectroscopy and calculation methods in a year to fully reveal the mechanism behind this discovery.
It turned out that during the research, the researchers found that in the cathode of the new fuel cell, water molecules participate in the oxygen reduction reaction but do not exist in large amounts, so the activation of water molecules has become a key factor. A new type of fuel cell developed based on this discovery is characterized by the use of non-noble metal catalysts.
This discovery not only reveals an important principle of fuel cell catalyst design, but also enables the performance of new fuel cell non-noble metal cathodes to a high level. (Reporter Li Wei)
