摘要

Integrating a power source, such as a direct methanol fuel cell (DMFC) into a low temperature cofired ceramic (LTCC) based microsystem allows for the next level of microsystem integration. In our LTCC-based DMFC structure, a porous silver tape is used to replace the traditional carbon electrode. Catalysts play a critical role in fuel cell performance. Two catalyst-preparing methods were evaluated, one cofired and one post fired, using platinum and ruthenium resinates for the catalysis source. The cofired anode microstructure demonstrated many whiskers with higher degreed Pt-Ru alloy and Ag while the post fired anode exhibited Ag, lower degreed Pt/Ru alloying and RuO_2. Cyclic voltammetry results show that the cofired catalyst has a better catalyst effect than that of post fired catalyst and both had a better catalysis performance that the catalyst on a standard carbon based anode. These specific catalyst microstructures contributed to the better catalysis effect in the methanol oxidation reaction (MOR) and the oxygen reduction reaction (ORR) respectively.
