碩士 === 中興大學 === 精密工程學系所 === 95 === This research aims to fabricate metallic bipolar plates by using micro electroforming technology for direct methanol fuel cells (DMFC) and assemble it into a single micro DMFC stack. Utilize negative type JSR-120N photoresist, with exposure the graph by lithography technology, and electroforming the flow channels on the metallic bipolar plates, which with 300μm thickness and 500μm width, and sputtering anticorrosive metal of 1.2μm. Finally using the 1.5×1.5cm2 MEA, assemble into a single micro DMFC. A metallic bipolar plates of single micro DMFC has been appeared successfully, the maximum output power density is 9.3mW/cm2 and maximum current density is 100mA/cm2, when the methanol solution is 8 vol.% at room temperature 30℃, and have suitable feasibility, hope to apply to offer the new energy of products of 3C in the future.
