Effect of Flow Fields and Scan Rates on Performance of Micro-DMFC
A micro-DMFC is a promising power source to substitute the lithium battery and used in the portable electronic devices. In this study, the effect of four types of flow fields of bipolar plates in a micro-direct methanol fuel cells (micro-DMFCs) on their performance were experimentally investigated. MEMS technology was applied in fabrication of micro-channel for the micro-DMFCs. The effect of the type of flow field design on the performance of micro-DMFCs was electrochemically evaluated for the four types of flow fields. The micro-DMFCs with double-channel serpentine presented the highest maximum power density and the micro-fuel cells with mixed multi-channel serpentine with narrow channels had the lowest maximum power density.
