Clever New Device Can Produce Hydrogen Fuel Using Water And Sunlight
Scientists are very keen to find effective ways of getting hydrogen from water, thus unlocking hydrogen's potential as a clean fuel. A newly developed device manages the feat, using only sunlight as a power source.
Using catalytic electrodes and perovskite solar cells fused together in a single unit, the clever contraption can hit sunlight-to-hydrogen efficiency rates as high as 6.7 percent. It just drops into water, and away it goes (when the Sun is out).
It might be a bit too early to start converting all our cars to take zero-emission hydrogen fuel cells, but the researchers behind the new invention say that it should be relatively easy to scale up the technology for wider use.
