EFFECT OF PARALLEL CHANNELS ORIENTATION ON TWO-PHASE FLOW AND PERFORMANCE OF A DIRECT METHANOL FUEL CELL
摘要
The effect of rotation angles on a direct methanol fuel cell's performance and carbon dioxide behavior is experimentally studied. For this purpose, a transparent window was added to the anode plate of the cell. The anode plate, with 14 parallel rectangular channels, is used in the test. The cross-sectional area of the channels is 2 mm × 2 mm, the ribs are 2 mm in width, and the channel is 52 mm long. By rotating the cell clockwise and counterclockwise in the vertical plane, the cell performance is investigated and compared to that in the vertical direction (0°). The experimental results show that when the cell is rotated the bubble size increases with the rotation angles and the bubbles slowly escape into the channels. The gas slugs move fast in the outlet manifold and the length becomes short when the cell is rotated in the clockwise direction. When the cell is rotated counterclockwise, gas columns appear at the exit side of the upper parts of the flow field. The amount of flow channels appearing in the gas columns increases with the rotation angles. In addition, the cell voltage is higher when the cell is rotated in the clockwise compared to the counterclockwise direction under the same rotation angle.
