摘要
简述了直接甲醇燃料电池(DMFC)的核心部件———膜电极(MEA)的结构及制备技术的最新进展,包括传统厚层电极法、薄层电极法、双层电极法、电沉积法和溅射沉积法,分析了各种方法的优缺点。其中电化学沉积法和溅射沉积法制备MEA,具有催化剂利用率高、负载量低、电池性能好等优点,若能实现大规模的工业化生产,将是DMFC最理想的MEA制备技术。为了进一步推广DMFC的商业化应用,降低MEA的制备成本,建议改进MEA组分、优化MEA结构和开发重现性好,同时适合工业化生产的MEA制备技术。
The advances in the structure and preparation techniques of membrane electrode assembly （MEA） for direct methanol fuel cells （ DMFC ） are reviewed. The advantages and shortcomings of the preparation methods, including traditional electrode method, thin-film electrode method, two-layer electrode method, electrodeposition method and sputtering method, are discussed. It is pointed out that the electrodeposition and the sputtering method,with thus fabricated MEAs＇ characteristics of high catalyst utilization, low catalyst loading and good cell performance, will be the ideal preparation techniques for DMFC if the production reaches large industrial scale. To promote the commercial application of DMFC and to decrease the cost of MEA production,it is necessary to improve the components, optimize the structure of MEA, and exploit the processes for MEA production which are reproducible and appropriate for industrial production.
