Researchers from Kyushu University in Japan published a paper in the weekly version of the German "Applied Chemistry" weekly magazine, saying that they have developed a new type of fuel cell using nickel and ruthenium as a catalyst. This discovery will help reduce the cost of fuel cells and thus promote fuel. The popularity of battery cars.
Fuel cell vehicles rely on hydrogen to react with oxygen in the atmosphere to generate electricity to drive the vehicle. Theoretically, only water is emitted. Therefore, fuel cell vehicles are called "environmentally friendly vehicles", attracting major auto manufacturers to compete for research and development.
However, most of the trial fuel cell vehicles currently use expensive platinum as a catalyst for extracting electrons from hydrogen, and the newly developed fuel cell of Kyushu University uses nickel less than 0.5 ‰ of platinum as the main raw material for the catalyst, so it is expected Significantly reduce costs.
A research team led by Professor Kojima Kosuke of Kyushu University developed a new nickel-based catalyst in 2008, and has been using this catalyst to develop fuel cells since. The new fuel cell can operate stably even under high temperature environment.
However, because the technology to reduce the resistance of the new catalyst has not made significant progress, the power generation of this new battery is still only about 4% of the time when the platinum catalyst is used.
