“…We prepared modified membranes by immersing them into 50 mL of ultrapure water (2 mS cm À1 ) containing 5 mmol of BMI$BF 4 , i.e., a concentration of 0.1 mol L À1 at room temperature, as previously described [22], and subsequently washing then with deionised water to remove any residual IL. This procedure was used because the IL can be incorporated by different processes, including cation exchange and physical adsorption [12].…”

“…The conductor exhibited good thermal stability, high ionic conductivity, mechanical strength and gas permeation comparable to those of hydrated Nafion. In the work of Padilha et al, the efficiency of the PEMFC was increased by 21% by wetting of the membrane electrode assembly (MEA) with an aqueous solution of 1-butyl-3-methylimidazolium tetrafluoroborate (BMIBF 4 ) ionic liquid (96). Employing the ionic liquid 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMIM][TFSI]) as the porogen, a novel asymmetric polybenzimidazole (PBI) membrane has been prepared by a soft-template method and used for high temperature proton exchange membrane fuel cells by Jheng and co-authors (97).…”

Ionic liquids have found widespread applications in electrochemistry, and are increasingly used in the field of electrochemical energy conversion and storage. In battery technology, the use of ionic liquids can increase the device safety significantly and help in enabling alternative technologies like Mg ion batteries. In fuel cell technology, new, water-free proton conducting membranes and new options for synthesis and improvement of catalysts are in the focus of research. In this paper some applications, advantages and drawbacks of ionic liquids in electrochemical energy technology are reviewed. Some examples from the authors' own work in batteries and electrocatalysis using standard electrolytes are presented, and the potential improvements by using ionic liquids in these studies are discussed.
