Аннотация

Study on mass transfer in cells under different factors is of great significance for improving the output capacity of direct methanol fuel cells. The influence of flow-field orientations on mass transfer in anode interdigitated channels of a liquid-feed direct methanol fuel cell is experimentally studied. The cell is at an angle of 30°, 60°, and 90° in the clockwise and counterclockwise direction, and characteristics of carbon dioxide bubbles and methanol solution flow are observed since the two-phase flow is directly related to the supply of reactants and discharge of products. Results show that the velocities of the carbon dioxide bubbles decrease as the channel rotates closer to the horizontal direction. The voltage decreases as the rotation angles increase.
