摘要
制备了基于电纺聚砜纤维网和短侧链Aquivion®全氟磺酸的纳米复合膜,并将其应用于质子交换膜水电解。即使在低纤维含量(5 wt%)下,纳米复合膜也表现出更好的机械性能和尺寸稳定性,保持了较高的质子导电性。用Aquivion®制备的EW为830 g eq−1的复合膜适用于水电解:特别是由增强膜组成的膜电极组件给出的I-V曲线与未改性膜相似。此外,纳米纤维聚合物组分在0.25 MPa的差压下可以有效降低氢交叉。
Composite short side chain PFSA membranes for PEM water electrolysis
Nanocomposite membranes based on electrospun polysulfone fibre web and short-side-chain Aquivion® perfluorosulfonic acid have been prepared for application in proton exchange membrane water electrolysis. The nanocomposite membranes showed improved mechanical properties and dimensional stability with respect to their non-reinforced counterparts even at low fibre content (5 wt%) maintaining high proton conductivity. The composite membranes prepared with Aquivion® with EW of 830 g eq−1 are suitable for water electrolysis: in particular the I-V curve given by a membrane electrode assembly comprising the reinforced membrane was similar to that obtained with a non-modified one. Moreover, the nanofibrous polymer component was effective in lowering hydrogen crossover at differential pressures of 0.25 MPa.
期刊介绍:
The Journal of Membrane Science is a publication that focuses on membrane systems and is aimed at academic and industrial chemists, chemical engineers, materials scientists, and membranologists. It publishes original research and reviews on various aspects of membrane transport, membrane formation/structure, fouling, module/process design, and processes/applications. The journal primarily focuses on the structure, function, and performance of non-biological membranes but also includes papers that relate to biological membranes. The Journal of Membrane Science publishes Full Text Papers, State-of-the-Art Reviews, Letters to the Editor, and Perspectives.
