Abstract: The gas-liquid flow in anode flow channel of micro direct methanol fuel cell (μDMFC) is simulated using the VOF method. The effect of channel sidewalls wettability on the gas-liquid transportation is investigated. Results indicate that improving hydrophilicity of the sidewall could promote removal of CO2 bubbles when the wettability of the sidewall keeps the same everywhere. When the wettability of the sidewall changes with height, the hydrophilic/neutral combinations have the highest pressure drop, but the hydrophilic/hydrophobic combinations have the lowest gas fraction in the channel. Comparing the two aspects, a conclusion was drawn that sidewalls with hydrophobic upside and hydrophilic downside facilitate the CO2 bubble removal and liquid transporting to GDL.
