采用多孔铜纤维烧结毡（PCFSF）制作了一种新型的质子交换膜燃料电池多孔流场。系统地研究了这种材料的可行性，包括制备、表征和应用。实验结果表明，较低的切割速度有助于防止纤维的成形失败和形态缺陷。较低的进给速率和较小的背切深度都减小了铜纤维的等效直径。烧结温度、时间和压力联合收割机共同影响PCFSF的成型质量，PCFSF具有开孔随机分布的三维网络结构。润湿性测试表明，PCFSF具有疏水性，接触角随孔隙率的增加而增大。PCFSF在模拟PEM燃料电池环境中的腐蚀行为表明，尽管铜在测试燃料电池中没有发生严重腐蚀，但未进行任何涂层和合金化处理的PCFSF并不完全胜任。电阻测试表明，复合双极板的总电阻小于石墨双极板。单电池测试表明，采用PCFSF流场的燃料电池性能是可以接受的。研究了阳极操作压力和阴极空气流量等操作参数对阳极氧化的影响。
A novel porous flow field made of the porous copper fiber sintered felt (PCFSF) is developed for proton exchange membrane (PEM) fuel cells. The feasibility of this material is systematically investigated involving fabrication, characterization and application. The experimental results reveal that a lower cutting speed helps prevent the fibers from formation failure and morphological defects. A lower feed rate and a smaller back-cutting depth both reduce the equivalent diameter of the copper fibers. The sintering temperature, time and pressure combine to affect the formation quality of the PCFSF which has three-dimensional network structure with open pores distributed stochastically. The wettability tests show that the PCFSF is hydrophobic and the contact angle increases with the increase of porosity. The corrosion behaviors of the PCFSF in simulated PEM fuel cell environment prove that the PCFSF without any coating and alloying treatment is not quite competent, although the Cu corrosion does not critically happen in the tested fuel cell. The resistance tests demonstrate that the combined total electrical resistance of the composite bipolar plate is smaller than the graphite plate. The single-cell tests show that the performance of the fuel cell with the PCFSF flow field is acceptable. The effects of the operating parameters such as the anode operating pressure and cathode air flow rate are also explored.
