摘要

本研究提出一種新型聚二甲基矽氧烷複合電極材料應用於可撓曲微型質子交換膜燃料電池，以聚二甲基矽氧烷做為基材，藉由微機電技術製作具有微流道結構之電極，透過有機矽烷方法在聚二甲基矽氧烷上修飾上特定官能基，並成長導電層金或導電高分子聚苯胺，分析其導電材料與PDMS基材間的附著力、表面形貌以及可撓曲電性測試，最後在沉積白金觸媒，進行燃料電池相關測試與分析。
　　有機矽烷修飾方法製作之PDMS金電極在附著力與可撓曲電性測試上皆具有非常突出的表現，附著力為ISO等級0，撓曲曲率達2/cm時電阻抗僅上升約8倍。燃料電池部分，半電池測試中，在撓曲曲率達3.333/cm時效能僅下降約6.6%；在全電池測試中，測得最大功率密度在0.321V時為2.55mW/cm2。

In this paper, a novel design of PDMS-based bendable electrodes with microstructures is proposed for flexible proton exchange membrane fuel cells (PEMFCs). The design of the bendable electrodes incorporates micro-structured PDMS-film to increase the reaction area and fuel pass-way, conducting layer Au with strong conjugation to the PDMS-microstructures for electron conduction, and Pt catalyst for fuel reaction.
The electrodes perform ISO class 0 in adhesion test and only increase 6.6% resistance under 2/cm bending curvature. The half-cell test yields a performance of 12.7~13.8mA/cm-2 at 0.6V under serious bending conditions and also 2.55mW/cm2 at 0.321V in fuel cell test.
