World’s smallest fuel cell to power gadgets
Check out the picture above of the smallest fuel cell in the world. This was developed by scientists at the University of Illinois which they believe is the smallest hydrogen fuel cell in the world. This could possibly be the new power source for gadgets in the future. This would mean that gadgets could have a more eco friendly power source and last longer at the same time.
This new cell utilizes only four components—a water reservoir and a chamber containing metal hydride separated by a thin membrane with an assembly of electrodes that conduct electricity underneath. Because of the small size of the cell, the team was able to eliminate the pump, pressure sensor, and controlling electronics that create such a power drain in typical fuel cells.
The current designs are capable of generating 0.7V at 0.1mA and work is underway for a model to generate 1mA – lasting for 30 hours!
