Apple Files Patent for Fuel Cell Battery
A renewed patent for fuel cell battery has been filed by Apple which could power its devices `for days or weeks’ a probable step to end battery life problem and an attempt to use more environmentally friendly ways of empowering creations. Initially revealed by source, the patents clarifies that the batteries would be better for Mother Nature as well as last for days or even weeks with a single charge.The two filings states that `our country’s continuing reliance on fossil fuels has compelled our government in maintaining complicated political and military relationships with unstable governments in the Middle East and has also exposed our coastlines as well as our citizens to the related hazards of offshore drilling. These problems have led to an increasing awareness and desire on the part of consumers to promote and use renewable energy sources’.
It further states that `due to this increased consumer awareness, electronics manufacturers have grown interested in developing renewable energy sources for their products and have been exploring various promising renewable energy sources like hydrogen fuel cells.
Hydrogen fuel cells have various advantages and such type of fuel cells and associated fuels could probably gain high volumetric as well as gravimetric energy densities that could possibly permit continued function of portable electronic devices for days or even weeks with the need of refuelling.
Designing Hydrogen Fuel Cell Systems – Challenging
But it is quite challenging in designing hydrogen fuel cell systems that could be adequately portable as well as cost effective to be used with electronic devices. As per the filing, Apple has been investigating on various kinds of fuel cells. Hydrogen fuel cells are the types found often in cars.However, Apple points out in the filing that building a hydrogen fuel cell which could fit in a laptop could be quite a challenge, but something that Apple would work on. The patent application which was published by the US Patent and Trademark Office defines a `portable and cost effective fuel cell system for portable computing device which could be utilised in various energy sources in providing long term power.
Apple had filed patents on the same topic many years back and very often patents ideas do not surface in their products. Though the new patent application suggesting various different energy sources from sodium borohydride to liquid hydrogen differs little from its previous filings, its renewal could indicate that Apple is keen on the idea.
Continued Operation of Portable Electronic Devices for Days/Weeks
The filing state that fuel cells could probably permit continued operation of portable electronic devices for days or also weeks without the need for refuelling. Recently revealed in The Telegraph was a major breakthrough by British firm Intelligent Energy stating that it had installed a hydrogen fuel cell in iPhone which had the potential of powering it for a week without any recharging.The patent seems to relate to MacBooks and constantly mentions that MagSafe connector utilised on laptop computers does not name check the `Lightning connectors used on the iPhone and iPad. Moreover, the patent also mentioned that the energy could come from a `fuel cartridge which is detachably affixed to the fuel cell system which means rather than recharging, one simply replaces the devices’ cartridge when it runs out.
