Zhao Tianshou, a lecture professor in the Department of Mechanical and Aerospace Engineering at the Hong Kong University of Science and Technology and his research team, recently won the second prize of the “National Natural Science Award†for the development of a fuel cell fueled with alcohols.
The National Natural Science Award is one of the five award categories under the “National Science and Technology Award†sponsored by the State Council. It is the highest-level national award in the field of natural sciences. Zhao Tianshou told the media at the Hong Kong University of Science and Technology on the 13th that this is an efficient and clean new energy technology that can be widely applied to mobile phones, computers, and automobiles.
According to the report, this study, “The Mechanism of Interaction of Heterogeneous Energy Transfer and Electrochemical Reaction in Fuel Cells,†provides an in-depth analysis of the physical and chemical processes in fuel cells, and succeeds in the unique method of cross-flow heat flow science and electrochemistry. The interaction mechanism of mass, energy transfer and electrochemical reaction kinetics in fuel cells was revealed, and a new theoretical framework was established.
Zhao Tianshou said that under this theoretical framework, the performance of direct methanol fuel cells has increased six-fold; the performance of direct ethanol fuel cells has increased four-fold. Methanol is industrial alcohol, and ethanol is edible alcohol. He pointed out that when alcohol is injected into a specially made battery box, it can be used as a battery.
Zhao Tianshou used the model car as a test and showed that he was charged with 5-cc of alcohol fuel and could run for 10 hours. He said that this is similar to the running time of gasoline; compared to current electric vehicles, the benefit is that there is no problem of long charging time and short walking distance. "It is certainly much cheaper to replace gasoline with alcohol, and the benefit is clean."
However, Zhao Tianshou added that this technology is still immature, especially the challenge of using ethanol as a fuel is relatively large. Because the research history is relatively short, there are still some technologies that need to be further overcome and improved. "In the future, we must increase efficiency, reduce costs in the long term, and increase the life of the battery..." Zhao Tianshou disclosed the next research direction. (Reporter Liang Jin)
