Hydrogen fuel cells, like those found in some “green” vehicles, have a lot of promise as an alternative fuel source, but making them practical on a large scale requires them to be more efficient and cost effective.
Apple is planning to make devices powered by hydrogen fuel cells, according to patent applications published by the U.S. Patent and Trademark Office.
The plans could create computers and phones with weeks-long battery power. It would also make the devices lighter and less bulky.
Technology using catalysts which make hydrogen from formic acid could eventually replace lithium batteries and power a host of mobile devices.
