Paper Abstract

CO2 gas bubbles have a great effect on the &mgr;DMFC (Micro Direct Methanol Fuel Cell) as the anode resultants. Visualization technique is one of the most important tools to study the formation, movement, and removal of CO2 gas bubbles. This paper presents an air-breathing micro direct methanol fuel cell made of PMMA for the visualization research. Four types of flow fields are fabricated in the anode plates. Different from the traditional &mgr;DMFCs, the stainless steel mesh is adopted as the current collector. The observation and study of CO2 bubbles behavior show that the quantities and bulks of CO2 gas bubbles increased as the current densities became higher. In addition, anode methanol solution flow rates and cell orientations also have complicated influence on the &mgr;DMFC performance.
