Invented a cheap way of electrolysis of water
Scientists from Stanford have demonstrated an inexpensive method of electrolysis of water, that is, the separation of H 2 O into oxygen and hydrogen. A simple AAA battery is sufficient to initiate the chemical process.
Scientists have used cathodes and anodes of nickel and nickel oxide, which has significantly reduced the supply voltage.
The Stanford experience is the first in the world when it was possible to abandon electrodes made of precious metals (platinum, iridium) for electrolysis, and when the process goes on at such a low voltage.

The research results are published in the journal Nature Communications (DOI: 10.1038 / ncomms5695).
This is a very important invention, because it simplifies the technology of manufacturing fuel cells with hydrogen. On one such cell, for example, a mobile phone can work for several decades. If you take a car for example, it will never need to be refueled (perhaps once every two or three years with intensive use). It is important that when using hydrogen fuel cells, the only by-product of combustion is water.
