Applications of PDMS Assembly Technology to Silicon-based Micro Direct Methanol Fuel Cell

在分析了PDMS应用优势的基础上,介绍了一种基于PDMS的封装技术,将此技术应用于硅基直接甲醇燃料电池的制作中,并对电池性能进行了测试。实验表明,PDMS封装技术能够有效解决封装的密封性、燃料输运导管固定、电池组件间的接触性等问题,并具有长期可靠性。应用PDMS封装技术的微型直接甲醇燃料电池性能优良,可以驱动一些低功率电子器件和MEMS器件。

Based on analyses of the advantages of PDMS material properties, this paper presented a set of novel and detailed PDMS assembly processes, which was used in the fabrication and test of a silicon-based micro direct methanol fuel cell (μDMFC). The results demonstrate that the PDMS assembly technology is able to solve the issues such as effectiveness of the cell package, the fixation of the feeding holes, the contact between layers and, at the same time, has long-term durability. The μDMFC prototype assembled by PDMS has achieved good performance and can be applied in low-power applications and MEMS devices.
