According to a new patent renewal filed by Apple, the company could be approaching an end to battery life issues with plans for a 'fuel cell battery' that could last weeks. The patent describes a "portable and cost-effective fuel cell system for a portable computing device."

The power could use a number of different energy sources – from sodium borohydride to liquid hydrogen – making it adaptable, and it is likely that it is geared towards MacBook laptops and smartphones. The filing further describes how the battery "can potentially enable continued operation of portable electronic devices for days or even weeks without refuelling." This could be the holy grail for busy executives on the go, who require constant connectivity. Stay tuned to Buro 24/7 Middle East for more on this invention as the story develops...
