iPhone maker Apple, this time, is ready to bring yet another change in its revolutionary products. According to patent applications filed by Apple and published by U.S. Patent and Trademark Office, the company is developing hydrogen fuel cell technology to power portable computing devices.
The patent application, entitled 'Fuel Cell System to Power a Portable Computing Device', says, "The disclosed embodiments relate to the design of a fuel cell system which is capable of both providing power to and receiving power from a rechargeable battery in a portable computing device. This eliminates the need for a bulky and heavy battery within the fuel cell system, which can significantly reduce the size, weight and cost of the fuel cell system."
"Our country's continuing reliance on fossil fuels has forced our government to maintain complicated political and military relationships with unstable governments in the Middle East, and has also exposed our coastlines and our citizens to the associated 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."
According to Apple, hydrogen fuel cells have a number of advantages. Such 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 refueling.
"However, it is extremely challenging to design hydrogen fuel cell systems which are sufficiently portable and cost-effective to be used with portable electronic devices."
