在被动式直接甲醇燃料电池(DMFC)的阳极中利用网状催化层(NNCL)结构的新型膜电极组件(MEA)导致DMFC的贵金属催化剂负载的显著降低。当NNCL中的PtRu(1:1)负载量为1.0 mg cm-2时,DMFC的最大功率密度约为1.0 mg cm-2。33.0± 1.9 mW cm−2,甚至略高于PtRu负载量为2.0 mg cm−2的常规MEA。电化学测试表明,与传统膜电极相比,这种NNCL的催化剂利用率大幅提高,阳极电荷转移电阻降低。这种新型膜电极的性能提高肯定是由于在阳极中形成了网状结构。该研究为降低质子交换膜燃料电池贵金属催化剂的使用量提供了一种新的途径。
A novel membrane electrode assembly (MEA) that utilizes a nanofiber network catalytic layer (NNCL) structure in the anode of a passive direct methanol fuel cell (DMFC) leads to a significant decrease in noble metal catalyst loading of a DMFC. When the PtRu (1:1) loading within the NNCL is 1.0 mg cm−2, the maximum power density of a DMFC is ca. 33.0 ± 1.9 mW cm−2, which is even slightly higher than that with a conventional MEA with a PtRu loading of 2.0 mg cm−2. Electrochemical tests show that such a NNCL exhibits a great increase in catalyst utilization and a decrease in charge-transfer resistance of the anode in comparison with the conventional MEA. The improved performance of the novel MEA is definitely due to the formation of the nanofiber network structure in the anode. This study provides a promising way to decrease the utilization of the noble metal catalysts for the proton exchange membrane fuel cells.
