World's smallest fuel cell coming to a gadget near you?
DVICE Atom Feed —
... chamber as vapor. There, it reacts to form hydrogen, which fills the chamber and pushes the membrane upwards, blocking the flow of water. The hydrogen is then gradually depleted, though, as it reacts at the electrodes beneath the chamber to create electricity.
The fuel cell generates 0.7 volts and a current of 0.1 milliamps for 30 hours before it runs out of fuel, but the engineers say the latest designs give currents of around 1 milliamp at a similar voltage.

... which is pretty long given the size of the cell. You can imagine that 0.7 volts and 0.1 milliamp current are not enough to power any gadget of yours, but of course, this mini-cell is just a step in development. However, the technology is good for mobile electronics such as smartphones because it does not use gravity to control the flow of water. Instead, it’s surface tension - and it also works when the device is moving. Find out more about the smallest fuel cell in the world on newscientist.com .
