The patent mentions that the energy could come from “a fuel cartridge which is detachably affixed to the fuel cell system”.

Batteries are the weak point in portable computers and mobile phones. And although batteries have become a little bit better, their loaded time is still limited.

Last week Apple filed a patent for a Macbook battery which will maintain for days, or even weeks.

The patent application

The patent application, published by the US Patent and Trademark Office, describes a “portable and cost-effective fuel cell system for a portable computing device” that could use a number of different energy sources to provide long-term power.(…) “can potentially enable continued operation of portable electronic devices for days or even weeks without refueling.”

A British firm in ‘Intelligent Energy’, told weeks ago that it had installed a hydrogen fuel cell in an iPhone that could power it for a week without recharging.

The patent mentions that the energy could come from “a fuel cartridge which is detachably affixed to the fuel cell system”, meaning rather than recharging, one would simply replace the device’s cartridge when it had run out.

It’s not clear how far Apple is with it’s development of this miracle battery.
