摘要：

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.　©　2018　by　Begell　House,　Inc.　www.begellhouse.com.
