Abstract:
1. A bipolar plate for a direct liquid feed fuel cell, comprising: a first fuel/oxidant path hole, through which fuel/oxidant is supplied and a second fuel/oxidant path hole, through which fuel/oxidant is discharged; a first manifold coupled with the first fuel/oxidant path hole and a second manifold coupled with the second fuel/oxidant path hole; and a plurality of flow channels each disposed to directly couple with the first manifold and the second manifold, and each flow channel covers a different area of the bipolar plate, wherein the flow channels communicate with the fuel/oxidant path holes, wherein fuel/oxidant flows are formed through the flow channels, wherein the flow channels are equally divided into a plurality of groups, wherein each flow channel of each group forms a serpentine flow path, and wherein the length of each flow channel is the same as the length of all other flow channels.
