摘要:  应用电化学方法研究了SPEEK膜的甲醇渗透性能.SPEEK膜具有比Nafion115膜低的甲醇渗透.以其作质子交换膜电解质组装的直接甲醇燃料电池(DMFCs)开路电压高于Nafion115膜组装的DMFC开路电压,但电池的放电性能尚待改进.本研究可为SPEEK应用于直接甲醇燃料电池提供一定的依据.

Abstract: This paper describes the methanol permeability characterization of SPEEK membranes and their feasibility for DMFC application. The SPEEK membranes showed a significant lower methanol permeation than Nafion~115 determined from voltammetric methods. An increase in open circuit voltage was found in the performance of SPEEK membranes in DMFC. The power density of the cell using SPEEK membrane was considerably poorer than that of Nafion~115. If modified properly, the SPEEK membranes can be chosen for DMFC application based on this study.

Key words: SPEEK, Methanol permeability, Direct methanol fuel cells(DMFCs)
