随着电子行业迅速发展，无线通讯设备和便携式消费电子产品不同类型的不断涌现，并为电池需求的快速增长也越来越多，而对电池的性能配置提出了更高的要求。现在普遍使用，例如，由于其成熟，性能发展空间越来越小，已很难做到的电子产品发展的要求，基本制造技术镍镉，镍氢和锂离子电池。因此，电子产品市场急需的高容量，环保的新电池，以取代目前广泛使用的电池。

微型直接甲醇燃料电池是直接使用甲醇作为一个质子交换膜具有体积小，重量轻，结构简单，能量密度高，低燃料来源丰富，成本，储存便携式燃料电池的燃料水溶液，安全等，而且还可以提供长期的电力，燃料的手机更换方便，笔记本电脑，相机，个人数字助理和医疗设备系统，如电源小型民用和军用单兵电源供应器，航天器电源，微电子等领域的系统电源机械便携式电子设备，以满足日益增长的能源需求，最有可能补充和替代目前广泛认为是理想的电池和电源。因此，微型直接甲醇燃料电池的研究和发展的电化学和能源正成为科学的研究方向和热点的主要领域。

微型直接甲醇燃料电池的研究起步较晚。中国科学院大连化学物理研究所中国科学院推出了利用小风扇，掌上电脑，玩具车和移动电话实验示范模型微型直接甲醇燃料电池。该研究所还使用作为复合层流体集硅表面的金属沉积物理气相沉积的方法，有效地降低了微型燃料电池内阻。微电子学研究所，清华大学在多孔硅大学为基础的微型燃料电池有一个深入的研究。中国科学院，上海微系统与信息技术研究所的微型燃料电池的结构，封装，系统集成研究方面也取得了良好的进展。

DMFC is expected to become the next generation of batteries - cheap and easy to carry a rich source of fuel

With the rapid development of electronics industry, wireless communications equipment and various types of portable consumer electronics products continue to emerge and the rapid growth of demand for batteries is also increasing, while for the configuration of battery performance put forward higher requirements. Now commonly used nickel-cadmium, nickel hydrogen and lithium-ion battery, such as basic manufacturing technology because of its sophisticated, performance development space is getting smaller and smaller, have been difficult to do the requirements of the development of electronic products. Therefore, the electronic products market a much-needed higher capacity, environmentally friendly new battery to replace the current widely used battery.

micro direct methanol fuel cells are the direct use of methanol-water solution as fuel for a proton exchange membrane fuel cell with a small size, light weight, simple structure, high energy density, fuel source rich in low-cost, storage portable, safe, etc., but also be able to provide electricity for a long time, the replacement of fuel convenience in mobile phones, laptop computers, cameras, personal digital assistants and medical device systems, such as power small civilian and military man-portable power supply, spacecraft power supply, micro-electro-mechanical areas such as system power portable electronic equipment to meet increasing energy demand, are most likely to complement and replace the current widely used as an ideal battery and power supply. Therefore, the micro direct methanol fuel cell research and development of electrochemical and energy is becoming a major area of scientific research orientation and hot spots.

our micro direct methanol fuel cell research started late. Dalian Institute of Chemical Physics, Chinese Academy of Sciences launched a used small fan, PDA, toy cars and mobile phones experimental demonstration model of micro-DMFC. The Institute also uses a physical vapor deposition method of metal deposition in the silicon surface as a set of composite layer fluid, effectively reduces the internal resistance of micro-fuel cells. Institute of Microelectronics, Tsinghua University on the porous silicon-based micro fuel cell had an in-depth research. Chinese Academy of Sciences, Shanghai Institute of Microsystem and Information Technology Research Institute of the micro fuel cell battery structure, packaging, system integration studies have also made good progress.
