    • Disclosed is a flow-field plate and fuel cell stack using the same. The flow-field plate (19) of the present invention comprises a center hole (5) formed at the center of flow-field plate, a inlet (6) and a outlet (7) formed on two positions near the outer edge of flow-field plate, and flow grooves distributing around the center hole (5) and communicating with the inlet (6) and outlet (7) on one side of flow-field plate. Since the flow-field plate according to the present invention comprises flow grooves distributing around the center hole and communicating with the inlet and outlet, which is benefit for oxidant diffusion, there is no “dead-end” on the flow-field plate and reactants may distribute uniformly to each part of flow-field plate. Furthermore, resultants generated from reaction, such as water, nitrogen, carbon dioxide, etc., may be discharged in time and not accumulate on flow-field plate. Therefore, the reactant utilization ratio, the fuel cell performances and its service life may be improved.
    • 公开了一种使用该流场板和燃料电池堆的流场板和燃料电池堆。 本发明的流场板(19)包括形成在流场板中心的中心孔(5),在流体外缘附近的两个位置上形成的入口(6)和出口(7) 以及围绕中心孔(5)分布并与流场板一侧的入口(6)和出口(7)连通的流动槽。 由于根据本发明的流场板包括围绕中心孔分布并与入口和出口连通的流动槽,这有利于氧化剂扩散,所以在流场板和反应物上没有“死端” 可均匀地分布到流场板的每个部分。 此外,由反应生成的产物如水,氮,二氧化碳等可能会及时排出,而不会积聚在流场板上。 因此,可以提高反应物利用率,燃料电池性能及其使用寿命。
