Apple has filed two patent applications related to Fuel Cell batteries for its devices, enabling them to run for weeks without requiring a recharge.
According to ZD Net, in the first patent titled ‘Fuel Cell System to Power a Portable Computing Device', the company notes that consumers want to use renewable energy sources for their electronic devices.
Fuel cells are capable of storing a lot of energy and don't take much device space as batteries do. However, the use of fuel cells in electronic devices could increase their costs.
"Fuel cells and associated fuels can potentially achieve high volumetric and gravimetric energy densities, which can potentially enable continued operation of portable electronic devices for days or even weeks without refuelling," Apple said in a patent application.
The second patent is related to making the fuel cell work alongside a traditional battery so that both are able to recharge one another.
Fuel cells are essentially used for portable charging for electronic devices but Apple is proposing to build fuel cells into the electronic device itself.
