專利摘要(中)
一種燃料電池雙極流道板與燃料電池電堆，所述雙極流道板包括第一氣體流道與第二氣體流道。每個氣體流道具有數條子流道，每條子流道都具有數個彎折部，且相鄰子流道的流向是相反的。兩個氣體流道的子流道在雙極流道板的反應區域內構成一幸運草狀（four-leaf clover type）圖案，其中所述幸運草狀圖案中的每個彎折部的彎折角度都在90度以內，以大幅降低燃料電池的流場壓力和阻力，可以提升電池的效能。

專利摘要(英)
A fuel cell bipolar flow field plate and a fuel cell stack are provided in which the bipolar flow field plate includes a first gas channel and a second gas channel. Each of the gas channels has several sub-channels, each of the sub-channels has bending parts, and the flow directions of adjacent sub-channels are opposite. The sub-channels of the two gas channels form a four-leaf clover type pattern in the reaction area of the bipolar flow field plate, wherein a bending angle of each of the bending parts in the four-leaf clover type pattern is within 90 degrees, so as to greatly reduce the flow field pressure and resistance of fuel cell, thereby improving the efficiency of the cell.
