The fuel cell is carried out primarily by oxygen or other oxidant, and chemical energy in the fuel is converted into electrical energy; as long as it can continue to add fuel, the fuel cell can continue to provide cleaning and inexpensive electrical energy. The battery has been widely used in electric vehicles and power generation devices;According to the physicist organization, the highlight of the study is a highlight of the study, and the jet fuel JP-8 can be used directly in the fuel cell without removing sulfur impurities or creates a high temperature work environment. Senior authors of the paper, from the Professor of the School of Materials Science and Engineering, Utah, said: "Our research proves that as long as the catalyst, JP-8 or other fuel can be used as a low-temperature fuel cell."
JP-8 is the aviation kerosene fuel used by the US military, with high temperature and cold, can work normally under extreme weather. It is very difficult to convert jet fuel to electric energy with traditional techniques. The fuel contains sulfur, while sulfur is precisely damaged metal catalysts used to oxidize fuel in conventional fuel cells. Moreover, this conversion is not high, even in the best conditions, only about 30% of chemical energy is converted into electrical energy.
In order to break through these limits, the researchers use JP-8 in an enzyme fuel cell, which is fuel in JP-8, which is a catalyst having a biocatalytic function as a catalyst. Such fuel cells are not only sulfur, but also work at room temperature. Specifically, the enzyme used is composed of alkane mono-oxygenase and alcohol oxidase, chemical properties and JP-8-like hexanes and octane are also experimenting as a test fuel. The researchers found that even if sulfur is added in the enzyme fuel cell, its power generation is not reduced.
In fact, the solid oxide fuel cell has been used by JP-8, but its operating temperature is above 950 Fahrenha's degrees. This study was the first time to achieve the utilization under room temperature conditions. Professor Acchole said that now, her team has confirmed the enzyme catalyst, and the next step will focus on how to design such a fuel cell and how to increase its electrical energy conversion efficiency.
