| 摘 要： | 研制了一种硅基微型直接甲醇燃料电池，其具有结构简单、质量轻、体积小以及比能量密度高等特点对点型、螺旋蛇型和栅型等流场结构进行优化设计模拟，从而为燃料电池极板设计提供可靠的依据．利用MEMS技术完成了这种微型直接甲醇燃料电池的制作，在对不同流场结构的实验研究中，发现栅型流场结构的微型直接甲醇燃料电池性能要好于其他流场结构，这与仿真结果一致．在常温下，当甲醇溶液物质的量浓度为1．5mol／L时，微型直接甲醇燃料电池最大输出功率密度为5．9mW／cm^2．

| Abstract: | A silicon-based micro direct methanol fuel cell （ μDMFC ） was presented in this paper, which bears the characteristics of simple configuration, small size and high specific power densities. Some field configurations were optimized by the simulation, and reliable proofs were provided for the optimized design of the plates of μDMFC. The silicon-based μDMFC was accomplished using MEMS technology, and the performance of μDMFC with the parallel flow field was better than those with the other flow fields at different flow field structures. The result is in conformity with that of the simulation. The maximum output power density of the μDMFC can reach 5.9 mW/cm^2 at room temperature when the molar concentration of methanol solution is 1.5 mol/L. |
