Beijing time on March 12, due to the development of battery technology lagged behind the development of science and technology as a whole, the evolution speed of mobile phones, no one was forced to slow down. Now there is a new fuel cell, it can completely change the way we charge, make the smart phone can be used for a week on a single charge, allow drones to extend the battery life for an hour.

Korea POSCO Engineering University researchers have developed a new fuel cell, it is a very small solid oxide fuel cells, only 1.95 mm diameter, battery electrolyte, porous stainless steel, thin film electrodes together, thereby greatly improving the thermal stability.
Launched periodical the journal nature published an article in the science report said Korea researchers develop micro solid oxide fuel cells (micro-SOFCs) using thin-film technology, battery energy density is very high, if you can successfully produced to replace part of the lithium-ion battery. Korea, researchers say, they adopt new technologies perforated stainless steel, thin-film electrolyte, heat capacity of small electrodes together, this is a major breakthrough, world no one had ever done before. Thermal and mechanical properties of porous stainless steel are very powerful, in terms of oxidation and reduction reactions is also stable.
Before the research team is using a silicon, the material defects, the component will soon decline, stability is not high, the actual use of the device needs to be quickly "on/off (on/off)" speed, silicon materials of the battery is not practical. After swapping with stainless steel, the researchers increased temperatures, prolongs the device's boot time, solve the mechanical problems, improving the chemical compatibility. In addition, the newly developed micro fuel cell manufactured using the casting process, from a business perspective to mass production of solid-oxide fuel cells. As a third-generation fuel cells, solid oxide fuel cell structure is simple, there is no corrosion and electrolyte overflow problem. Moschino Samsung Note3 case
When oxygen ions to transfer fuel electrode through the oxide electrolyte fuel cells turn hydrogen into electricity. In 1022 camera degrees Fahrenheit (550 Celsius) conditions, the energy density of solid oxide fuel cells can reach each cubic centimeter of 560 mW (1MW=1000KW). During the process of rapid thermal cycling, the energy density of batteries we can maintain the same.
