【摘要】 利用正交实验设计法优选出PEMFC电极催化层制备的最佳条件,即制备所谓的亲水电极,催化层中不含PTFE,提高Nafion的含量,尽可能降低Pt含量。当Nafion的含量为1.4mg·cm^-2,Pt含量为0.4mg·cm^-2,在该工艺条件下,以常压的H₂和空气分别作为燃料气和氧化剂,电池的最高功率可达到0.37W·cm^-2。研究表明,提高Pt/C中的Pt含量将是提高催化剂性能的有效途径。更多还原

【Abstract】 The optimal composition of catalyst layer in PEMFC electrode was prepared through orthogonal method, which is called hydrophilic electrode. There is no PTFE,more content of Nafion and as low as possible of Pt in the catalyst layer. According to this condition, the power density of PEMFC attained 0. 37 W · cm-2 when the Nafion loading was 1. 4 mg · cm-2, and the Pt loading was 0. 4 mg · cm-2 in the catalyst layer, using H2 as fuel and air as oxidant both at atmospheric pressure. Additionally, results showed that increasing Pt loading of Pt/C catalyst was a reasonable way to improve PEMFC performance.更多还原
