This amazing discovery was made by US chemical engineers which have create the world’s smallest fuell cell( only 9 cubic millimeters). We have to whait some time util this fuel cell to be released on the market because is currently a prototype.
The scientists from the University of Illinois at Urbana-Champaign created the cell using 4 components: a thin membrane, an assembly of electrodes, a water reservoir and a chamber containing metal-hydride. Even when this device is rotated and moved, it will continue to work.
Small holes in the membrane let the water molecules reach the chamber as vapor. The vapor then reacts with the metal hydride to form hydrogen, which fills the chamber, pushes the membrane up, and blocks the flow of water.
This amazing fuel cell could power simple electronic systems and microrobots.
