摘　　要：采用计算流体动力学(CFD)技术对质子交换膜燃料电池(PEMFC)、阳极燃料气体(H2)流场进行了数值模拟,以最大燃料气体(H2)利用率为目标进行了流场板沟槽尺寸优化.结果表明,当沟槽宽度为1.5mm,脊部宽度为0.5mm和沟槽深度为1.5mm时,燃料气体(H2)的利用率达到最大值84.8 .With computational fluid dynamics techniques,numerical simulation of flow field of fuel gas (H2) at the anode of PEMFC was carried out to optimize thechannel dimension of the flow field plate of PEMFC to reach maximum fuel gas (H2) consumption. The optimum dimension for channel width, land width and channel depth were close to 1.5, 0.5 and 1.5 mm respectively, and the maximum fuel gas(H2) consumption at anode is 84.80/0.
