Graphene breakthrough could trigger electric car revolution: Proton discovery paves way to super-efficient batteries

Greetings,

Graphene breakthrough could trigger electric car revolution: Proton discovery paves way to super-efficient batteries

Graphene is the world’s thinnest and strongest material that is impermeable to atoms and molecules
Researchers from the University of Manchester were surprised to find that positively charged hydrogen atoms – protons – can pass through it
Discovery could boost efficiency of fuel cells for cars generating electricity from hydrogen, by using a graphene-based membrane

Scientists have discovered a surprising new property of graphene – the world’s thinnest and strongest material – that could accelerate the development of electric cars and other green technologies.
Researchers have found that the newly discovered type of carbon graphite, which is found in pencil lead, allows positively charged hydrogen atoms or protons to pass through it.
Their discovery could increase the efficiency of fuel cells for cars, because the cells generate electricity from hydrogen.

The researchers, led by Nobel Prize winner Sir Andre Geim of Manchester University, who discovered graphene, said their finding raises the possibility that, in future, graphene membranes could be used to ‘sieve’ hydrogen gas from the atmosphere to generate electricity.
This is because the one-atom thick material acts like a filter to allow protons to pass through it, while blocking the passage of other atoms…..MORE HERE
