The paper published in science on July 10 was withdrawn.
This is also the first time that the Chinese scientific research team has been withdrawn by science.
The withdrawal time is only two months from the query raised by pubpeer, an academic anti-counterfeiting website.
The corresponding authors of the withdrawn paper are Professor Zhu bin of the school of energy and environment of Southeast University, and associate professor Song huaibing of the school of materials and chemistry, China University of Geosciences. The first author is Associate Professor Wu Yan.
In the withdrawal letter, the team explained:
The wrong use of pictures in the paper is due to poor communication under the epidemic situation. The paper will be finalized from mid December 2019 to March 2020. During this period, Wuhan city is closed. The author can only communicate between different cities.

Three months ago, the team of Zhu bin and song huaibing published a paper on solid electrolyte of fuel cell on science.
Not long after that, professional academics played dummyElisabeth BikFocus on the papers in pubpeerS10andS9bTwo experimental charts were questioned.
Elisabeth bik believes that the experimental pictures of this paper published in science are highly similar to the two papers published on ijhe before.

As for the S10 picture, the team explained:
The experimental image was previously saved in the experimental database, but an error occurred when computer data was transferred from one student to another.
For S9b pictures, the team said it was when drawing pictures
The reason is that the data test of figure s9b and figure 8b in ijhe's 2018 paper was conducted in the same period of time, and the experimental data were similar. Therefore, these data were wrongly saved in the same folder and finally drawn into a map, resulting in s9b containing the data in the 2018 paper by mistake.
Afterwards, the team repeated the experiment to reproduce the data and found two NaxCoO2/CeO2(x
As to why these errors were caused, the team said they were related to recent changes in location and personnel.
In June and September 2019, all laboratories of the school of materials and chemistry of China University of Geosciences moved to the new campus 30 km away. At the same time, the author, L. Liu, graduated and temporarily interrupted data transmission to his successor.
The manuscript novel coronavirus pneumonia was completed in mid December 2019 to March 2020, when Wuhan was closed due to the new crown pneumonia outbreak in 2019. All authors preparing manuscript and supplementary material data are isolated from each other in different cities and countries without access to laboratory computers or database resources, resulting in communication errors.
Finally, the team said in the withdrawal letter that:
We are fully responsible for unexpected errors in the supplementary materials. We adhere to the experimental design, theoretical calculation, main data and analysis of low temperature proton ceramic fuel cells. However, in view of the errors in the supplementary material, we decided to withdraw the report.
All authors except Zhu bin, M. Huang, M. Akbar and JS Kim agreed to withdraw the manuscript.
Embarrassingly, three months ago, the cover paper of nature from the team of Xing Lida from China University of Geosciences (Beijing) was also withdrawn, becoming the first paper in the Chinese academic community to be withdrawn by nature.
