Apple has filed a patent for a fuel cell battery that could power its devices for “days or even weeks”, according to a report by Business Insider.
The US patent application describes a “portable and cost-effective fuel cell system for a portable computing device”.
No details about how the fuel cell would be powered were released, and the publication did note that a patent application does not mean the product will be in development in the near future.
The filing says fuel cells “can potentially enable continued operation of portable electronic devices for days or even weeks without refueling”.
News of Apple’s fuel cell patent follow recent reports that Intelligent Energy in the UK developed a working iPhone 6 with a hydrogen fuel cell built into the chassis.
