How to reduce fuel power lithium batteries to reduce platinum metal dosage

　　As we all know, the fuel power battery is very environmentally friendly because its combustion product is important. Recently, the University of Copenhagen has made new progress on fuel power batteries. No need to use precious metal platinum as a catalyst, and it can also make the supply of fuel power batteries the same as the same power battery that is currently using platinum catalysts. This scientific discovery has been published in the "Natural Materials" magazine.

　　Cheaned hydrogen fuel cars and new fuel power battery design

　　Researchers have shown that fuel power batteries should replace internal combustion engines as sources of power for future cars. They have little effect on the climate environment. On the one hand, because the fuel power battery has higher fuel, on the other hand, its combustion products do not contain smoke, dust, carbon dioxide and other substances.

　　The technical bottleneck currently encountered by fuel power batteries is that the platinum metal catalyst used in the meantime is appropriate and expensive. This is the biggest obstacle to the development of fuel power batteries.

　　Reduce the use of precious metals

　　Matthiasarenz, an associate professor of chemistry at the University of Copenhagen, tested a series of different catalysts with the discussion at the Study at the University of Monnis University and Dussertolf Planck.

　　He showed: "We found a new way in the laboratory to use one -fifth of the platinum metal in the normal hydrogen fuel power battery to achieve the same capacity as it. But it is certain that the new method can reduce the reliance on platinum catalysts. It has taken a big step in the reduction of fuel power batteries. "

　　Platinum metal is one of the rare most rare metals on the earth. Most of the platinum metals exist in South Africa, with 80%of the world's content, while platinum reserves in the Russian region account for 10%of the world's.

　　In 2012, the global platinum metal output value was 179 tons. The global annual output value of gold reaches 2700 tons. For comparison, platinum is particularly valuable. The price of 1 ounce platinum is $ 1600.

　　Listed, particle or nanoparticles

　　The fuel power battery uses platinum as a catalyst and presented electrical energy through hydrogen and oxygen. The best response mode is to cover the platinum metal layer during the response, but the cost is high. Therefore, the shape of platinum metal in modern fuel power batteries is made into granular. The so -called new method of the seminar team is to place granular platinum metal more scientific and more efficient.

　　The same quality platinum metal presents a 5x electricity volume

　　During the test, traditional catalysts can generally present 1 ampel current per milligram. The Copenhagen seminar team used 1 mg platinum metal to generate 8 ampel current. At the beginning, the discussion thought it was because of the smaller particles of platinum presenting higher powerield (Powryield), but after further observation, they had a more amazing discovery.

　　The phenomenon discovered by accident

　　They make platinum metal particles into a series of different volumes. They found that the density of platinum particles was very high on certain sample catalysts. Reselutes depict it as "ParticleProximityEffect". The next step is to do the use of industrial measures to achieve this "nearby effects" on a large scale.
