iPhone users have long yearned for a power solution that would power their handsets for more than a few short hours, and British power tech company Intelligent Energy just might have the answer.
The Telegraph reports that Intelligent Energy has developed an iPhone 6 prototype that boasts a built-in fuel cell that uses hydrogen cartridges that will deliver up to a week’s worth of power.
The company’s patented fuels cell system creates electricity from the chemical reaction of hydrogen and oxygen, which creates power when combined, and produces only a small amount of water and some slight heat as waste.
While Intelligent Energy has already debuted a hydrogen-powered iPhone charger, this latest breakthrough allows the fuel cell portion of the technology to fit alongside the iPhone 6’s battery, without the need to alter the size of shape of the handset.
The only noticeable difference to the iPhone 6 prototype was the addition of rear vents, which allow a small amount of water vapor to escape. The device also sported a modified headphone socket for refueling hydrogen gas, likely because it was a prototype.
Intelligent Energy says it has plans to sell a disposable hydrogen fuel cell cartridge that will attach to the bottom of a smartphone, supplying power enough for a week’s worth of “normal use.”
