Sony Hybrid Fuel Cell System  (Source: TechOn)
Sony plans to commercialize the hybrid fuel cell system for mobile devices

Fuel cells are one of the items that will change the face of the electronics industry forever once they finally start making their way into electronic devices. Sony unveiled its own ultra-small hybrid fuel cell system that is small enough to fit in one hand.

The fuel cell system measures 50mm x 30mm and combines a fuel cell, Li-polymer secondary battery and a control circuit. According to TechOn this is the first time Sony has shown off a complete fuel cell system that has a control circuit and secondary battery.

Sony says that it expects to commercialize the fuel cell and an engineer from the Sony material Laboratory said, “We have been aiming to mount (a fuel-cell system) in mobile devices and finally reached a level of commercial design.” The fuel cell runs on methanol.

Methanol also powers the Mobion fuel cell that DailyTech covered last week that was integrated into a GPS prototype. However, the Mobion fuel cell is passive and the Sony fuel cell is active with a pump to move the methanol. Sony’s didn’t comment specifically on its fuel cell power output, but does say output can be as high as 3W.

According to Sony, 3W is enough power for a mobile device. The fuel cell is said to be able to run 14 hours in a mobile phone on 10mL of methanol. It’s not entirely clear if the fuel cell will power electronic devices directly or if it will charge the internal Li-ion battery, which will in turn power the electronic device the fuel cell is integrated into. The battery could also be used as a type of backup power system.

Methanol is used quite frequently for RC cars and planes. It's also used as the fuel for funny cars and as windshield wiper fluid. It's no more dangerous than any other pure alcohol. I've been using it in my RC planes for years. I've spilt it on myself. I'm still alive and healthy. You pretty much have to be huffing or drinking the stuff for it to be fatal. 10ml certainly isn't going to kill you.

Speaking of RC, I'd love to get my hands on one of these so I'd never have to charge batteries again. It would need to be more than 3w though.

For ingestion purposes, methanol is much more toxic than ethanol.

Even a small amount can cause blindness.

Wikipedia is good for pointing you in the right direction, like a friend who knows a little bit about what you were looking for. Dont use it as a source, but usually it is pretty good.

"If you look at the last five years, if you look at what major innovations have occurred in computing technology, every single one of them came from AMD. Not a single innovation came from Intel." -- AMD CEO Hector Ruiz in 2007
