Tech giant files a patent application for a built-in fuel cell system

With all the goods that comes from electronic gadgets, it is a common knowledge that battery life is a big issue, a lot of stop gaps has been developed to fix this in different ways and capacities. While a number of different products have been developed for charging
electronics devices, few have taken off. Typically, fuel cells for electronics are
designed for portable charging, in which a person carries a fuel cartridge
that's about the size of a roll of coins and can recharge a smartphone or
music player. But Apple envisions fuel cells built directly into electronics.
The way fuel cells create electricity is by combining a fuel, such as
hydrogen, with an oxidizing agent, like oxygen or air. The technology has
gained increased attention over the past few years because not only could
it replace batteries, it could also be used as an alternative to traditional
fossil fuels, like oil and gas.
While hydrogen is a common source of fuel for the technology, Apple's
patent outlines a number of potential fuel sources, including sodium
borohydride and water, sodium silicate and water, lithium hydride and water,
magnesium hydride and water, among others -- including liquid hydrogen
and compressed hydrogen gas.
This isn't Apple's first patent application for a fuel cell system. In 2011, the
company filed a similar application for such a system for a "portable
computing device." In March, the USPTO published an Apple patent
application for an external fuel cell system to power mobile devices.
This is a significant move to market dominance from the IOS producer.
