Recently, a research team led by Prof. Nanwen Li from the Institute of Coal Chemistry (ICC) of the Chinese Academy of Sciences (CAS), cooperating with (Prof. Qingfeng Li’s group from Technical University of Denmark and Hongying Tang’s group from Tianjin Normal University), presented that the polymers of intrinsic microporosity (PIMs) with strong hydrogen-bonding functionalities can improve phosphoric acid (PA) binding energy and thus preferably uphold PA in the vicinity of Pt catalyst particles to mitigate the adsorption of PA on the Pt surface.
This study entitled “Low Pt loading for high-performance fuel cell electrodes enabled by hydrogen-bonding microporous polymer binders” was published in the Nature Communications on 08 December 2022.
This work was supported by National Natural Science Foundation of China (No. 21835005 and No. 52G15023), etc.
