Bulky mobile batteries may become a thing of the past, after designs for a hydrogen fuel cell have been patented by Apple. The light-battery technology could power iPhones and laptops for up to several weeks, without being recharged.
As a green-bonus, hydrogen fuel cells are a renewable energy source that converts oxygen and hydrogen into water, heat and electricity. However, the technology – which has long been touted as the future power source for cleaner, greener cars, may be a challenge to master as a portable and cost-effective source for electronic devices.
Apple documents filed with the US Patent and Trademark Office say “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,” the UK’s Daily Telegraph reports.
“These problems have led to an increasing awareness and desire on the part of consumers to promote and use renewable energy sources.”
It could be a while until the new technology hits the market, but it may be the big breakthrough consumers have been waiting for in the smartphone industry.
