The university of Illinois researchers have some big news in the way of the world’s smallest working fuel cell. You know the rumored power of the future, just in a very very very small package. So small as you can see in the image it’s smaller than most watch batteries. In fact the fuel cell measures in at only 3mm x 3mm x 1mm and is comprised of only 4 layers. The water reservoir, the thin membrane that makes it work, a chamber of metal hydride and of course the teeny tiny electrode assembly.
The tiny fuelcell packs low voltage coming in at 0.7 volts and 0.1 milliamp current that it can push for about 30 hours. A newer version is said to boost the milliamperage up to a full milliamp. Of course this is definitely not enough to go powering a cell phone or a TV or anything like that. It could however be used for smaller electronics and you know things like the microbots and those swarm bots we heard that Darpa wants to build.
