要約

The CO2 gas bubble behavior in an anode channel and the performance of a transparent direct methanol fuel cell (DMFC) were experimentally investigated. To observe the gas–liquid two-phase flow, the transparent anode plate was made of polycarbonate, and the anode end plate possessed a 70 mm × 70 mm window. The emergence, growth, and coalescence of the CO2 bubbles were recorded by a high-speed camera at 250 frames/s−1. The DMFC was tested and observed at different current densities, methanol flow rates, and temperatures, which exhibited an obvious influence on the CO2 gas bubbles' behavior. It was observed that the bubble size increased with the current density and temperature, while the bubble number obviously decreased downstream in the channel. On the other hand, the bubble behavior, particularly its size and gas volume, affected the internal mass transfer of the DMFC and therefore affected the cell performance.
