Stanford University experts have found a way to create an energy source that replaces gasoline extremely cheaply with water and rabbit batteries.
New energy source to replace gasoline
For a long time, we have been relying too much on fossil energy sources , especially oil. For that reason, scientists are constantly seeking to replace them with new, cleaner and safer, new energy sources .
Hydrogen material is a much-expected solution. However, before, to produce hydrogen, humans needed rare and precious metals such as platinium and iridium. Therefore, the cost of producing hydrogen is too large.
But it will all be a thing of the past with the new device created by Stanford University experts. This is an electrolytic machine that helps extract hydrogen from water at a very low cost. The materials that make up the device only include one nickel, iron and a 1.5V battery.
The device works continuously for 7 days without problems!
The reason the electrolytic device produces a lot of hydrogen is due to the construction of two electrodes from nickel oxide - iron. Small canopy into metal particles pressed together increases the water contact area of the two poles. Thus, hydrogen is produced more and consumes less energy.
Chemical mechanism when water electrolysis
Yi Cui, a Stanford professor of materials science and engineering, commented: 'This process produces very strong micro-particles, so the catalysts have good and stable conductivity. Moreover, the use of nickel and iron catalysts is more advantageous because of its low cost. '
Haotian Wang , the inventor, said: "This electrolytic device is very stable, can maintain itself for 1 week with an efficiency of 82% at room temperature."
