DMFC is expected to become the next generation of battery

With the rapid development of electronics industry, wireless communications equipment and various types of portable consumer electronics products are emerging and rapid growth in demand on the battery are also increasing, while the battery is configured and set higher requirements. The now widely used in nickel-cadmium, nickel hydrogen and lithium ion batteries because of their basic mature manufacturing technology, property development space getting smaller and smaller, have failed to accomplish electronic product development. Therefore, a kind of electronic products market need higher capacity, environmentally friendly new battery to replace the current widespread use of batteries.dell wu946 battery

Micro direct methanol fuel cell is the direct use of methanol as a fuel aqueous solution of a proton exchange membrane fuel cells, small size, light weight, simple structure, to high density fuel source rich in low-cost, storage, portable, safe, etc. characteristics, but also to provide electricity continuously for long time, to facilitate replacement of the fuel, which in mobile phones, laptop computers, cameras, personal digital assistants and medical Zhuangzhi system power small civilian and military man-portable power, spacecraft power, Wei Dianzi Mechanical systems such as power portable electronic devices to meet the increasing needs of high-energy, most likely complement and replace the current widespread use of battery and an ideal power supply. Therefore, micro direct methanol fuel cell research and development of electrochemical and energy is becoming one of the main directions of scientific research in the field and hot spot.dell studio 1558 battery

China in the micro direct methanol fuel cell research started relatively late. Dalian Institute for Chemical Physics, Chinese Academy of Sciences released a used small fans, PDA, toys, cars and mobile phones Experimental demonstration model of micro-DMFC. The Institute also by physical vapor deposition on silicon composite layer of metal deposited on the surface as a collector, effectively reducing the internal resistance of micro fuel cells. Institute of Microelectronics, Tsinghua University, based on porous silicon micro fuel cells in-depth research. Shanghai Institute of Microsystem and Information Technology Institute of the micro fuel cell battery structure, packaging, system integration and other aspects of the research has also made good progress.dell studio 1557 battery
