摘　　要：微型燃料电池被认为可作为便携式电子设备的下一代电源而越来越受到关注。传统的石墨、金属等材料用于微型燃料电池时产生了不少问题,如石墨材料微加工性能差,金属易腐蚀、密度较大等不利于其应用于便携式设备。硅材料因为其低的气体透过率、高的导热系数和适于微加工等特性在微型质子交换膜燃料电池中得到了越来越多的应用。本文对硅材料在微型燃料电池的气体扩散层、质子交换膜构造中的应用以及硅材料作为基底制作微型燃料电池技术的进展进行了综述,并对硅材料在微型燃料电池领域应用的技术特点及前景做了分析与讨论。Micro fuel cells have drawn increasing attention because they are promising choice of next generation power sources for portable electronic devices. Several problems, such as poor micro-machinability of graphite, corrodibility and high density of metal, rise when the conventional materials such as graphite and metal applied in micro fuel ceils. The application of silicon material in micro fuel cells is becoming popular because of its low gas permeability, high thermal conductivity, good property for micro processing. The application of silicon material in fabrication of gas diffusion layer and proton exchange membrane of micro fuel cells is introduced. Packaging technique of micro fuel cell based on silicon material is reviewed. The analysis and discussion of distinguishing feature and long-term potential of the application of silicon in micro fuel ceils are conducted.
