According to the news from Patently Apple, a foreign technology blog, Apple recently submitted a patent on fuel cells. According to the patent, Apple can use a special medium to control the multiple operations of the fuel cell after the small device is connected to the battery, and realize the application of the fuel cell on the small device (mobile phone).

Fuel cell is a kind of battery that converts the chemical energy of fuel into electric energy through the chemical reaction of fuel. Its advantage is that the energy conversion efficiency is high, and it can be used for a long time by adding fuel without charging.

Previously, foreign media also disclosed that Apple has obtained a patent for the layered battery system technology, which can achieve more efficient lithium battery applications, and has improved the endurance and charging speed. Because the layered battery technology has been developed for 10 years, the industry generally believes that this technology will break out this year.
