The battery life of Apple devices could soon receive a significant boost, not of hours, but of weeks, according to the patent filed with the U.S. Patent and Trademark Office.
On Thursday, the U.S. Patent and Trademark Office published Apple’s application for patent for a “Fuel Cell System to Power a Portable Computing Device”.
The new technology that Apple is working on would be tantamount to a weeks of forging your Mac without recharging. A revolutionary application of fuel cells could improve the battery life of the Apple devices.
Initially, the patent application was reported on the 9to5Mac website. Here, it was discussed how Apple intends to use fuel cells as a cost-effective technology which, packed into a portable device wouldn’t prove a burden in terms of weight while providing a significant power boost.
Fuel cell technology is already present on the market for electronic devices. Yet, while the size of a fuel cell charger is no bigger than a coin-roll, it is external and designed specifically for portable charging.
Taking this technology one step further, Apple envisages fuel cell power sources in-built in its devices, particularly Macs. The patent application of the tech giant listed as potential fuel sources hydrogen and compressed hydrogen gas, magnesium hydride and water, lithium hydride and water, sodium silicate and water, sodium borohydride and water.
Conventionally this technology is based on combining hydrogen as a fuel source with oxygen or air acting as an oxidizing agent. In the past years, fuel cell power sources have captured everyone’s attention as their potential to be used instead of traditional fossil fuels is immense once the technology really takes off.
In 2011, Apple filed a separate application for a patent listing the development of a fuel cell system for a portable computing device. In March, another publication of the U.S. Patent and Trade Office listed a patent application coming from Apple for an external fuel cell system.
It is still unclear whether Apple will be making an official announcement soon and if the technology will be available in the next years, as the company did not comment as of yet.
Another rumor circulating on tech blogs and websites is that Apple has partnered up with Intelligent Energy to develop a separate fuel cell system that would be incorporated into its iPhones, also increasing their battery life.
