摘要

近年來利用低溫共燒陶瓷（LTCC）技術在三維的反應流及微流體元件之研究十分受到矚目。在本文中，我們使用此技術研製可完全整合觸媒鉑的微型燃料重組器，其中的微流道可以直接與觸媒鉑藉由共燒的方式來整合而無需其他方法，另外不同厚度（10和40 nm）的觸媒鉑對重組器效能的影響也在此文中深入探討。本研究使用甲醇為碳氫化合物的來源，然後量測反應後所產生的碳氫燃料，其中包含氫氣、一氧化碳和甲烷。結果顯示當重組器的觸媒鉑厚度為10 nm，流率為1 ml/h，溫度為300 °C時，能產生最多的氫氣。整體而言，LTCC技術是個極為簡單且可靠的微製程，用以製作的微型燃料重組器能與觸媒鉑完全整合且具可靠度。

Applying low temperature co-fired ceramic (LTCC) tape technology on constructing complex 3-D reacting flow and microfluidic devices has drawn increasing attention. In this paper, we developed a fully integrated micro-scale fuel reformer over Pt catalyst using LTCC tape technology, and we showed that the microfluidic channels and Pt catalytic layers in a LTCC reformer can be integrated by direct co-firing without additional processes. Current study also compared the effect of different thicknesses of Pt catalyst (10 and 40 nm) in LTCC reformers. As a source of hydrocarbon, methanol was used and the production of hydrocarbon fuels, including hydrogen, carbon monoxide and methane, was measured by gas chromatography. Among different parameters tested, our results revealed that a LTCC reformer coated with 10-nm Pt catalyst can generate most hydrocarbon fuels at a flow rate of 1 ml/h at a temperature of 300 °C. Overall, LTCC tape technology is a simple, reliable method to fabricate a fully integrated micro fuel reformer.
