高温质子交换膜水电解用Nafion/BN复合膜的制备与性能研究
Preparation and performance investigation of Nafion/BN composite membrane for high temperature proton exchange membrane water electrolysis
摘要
Abstract
To circumvent the deleterious effect of water depletion and enhance the protonic conduc-tion at elevated temperatures in proton exchange membrane water electrolysis,Nafion/BN composite membranes have been ingeniously contrived,utilizing boron nitride(BN)as a novel hygroscopic modifier.The inherent alkaline moieties presented on BN's surface engage in a synergetic acid-base interplay with the sulfonic acid groups of the Nafion matrix,establishing a robust hydrogen-bonded lattice that significantly expedites proton translocation.The scanning electron microscopy(SEM)and X-ray energy dispersive spectroscopy(EDS)assessments affirm the homogeneity of BN's dispersion within the membrane.Water uptake assays articulate a substantial augmentation in the membrane's hygroscopicity attributable to BN's incorporation.Successive evaluations of proton conductivity cor-roborate BN's efficacy in elevating the membrane's ionic conduction capabilities.In practical appli-cation,the Nafion/BN composite membrane manifested superior performance in water electrolysis at 130℃,achieving a notable current density of 2.04 A/cm2 at a potential of 2.0 V.The findings portend a promising trajectory for Nafion/BN composite membranes within the realm of high-temperature proton exchange membrane water electrolysis.关键词
