“…Consequently, the performance of the resulting membranes was enhanced and a current density of 0.217 A/cm was observed [69]. Zanchet et al [76] fabricated Nafion composite membranes and varied the ILs content, namely 3-triethylammonium propane sulfonic acid tetrafluoroborate (TEA-PSBF 4 ), 3-triethylammonium propane sulfonic acid hydrogen sulphate (TEA-PSHSO 4 ), and 3-triethylammonium propane sulfonic acid trifluoromethanesulfonate (TEA-PSCF 3 SO 3 ). The ILs were reported to improve the proton conductivity and stability of the resulting membrane.…”

This work provides a comprehensive review on the incorporation of ionic liquid (ILs) into polymer blends and their utilization as proton exchanges membranes (PEM). Various conventional polymers that incorporate ILs are discussed, such as Nafion, poly (vinylidene fluoride), polybenzimidazole, sulfonated poly (ether ether ketone), and sulfonated polyimide. The methods of synthesis of IL/polymer composite membranes are summarized and the role of ionic liquids as electrolytes and structure directing agents in PEM fuel cells (PEMFCs) is presented. In addition, the obstacles that are reported to impede the development of commercial polymerized IL membranes are highlighted in this work. The paper concludes that the presence of certain ILs can increase the conductivity of the PEM, and consequently, enhance the performance of PEMFCs. Nevertheless, the leakage of ILs from composite membranes as well as the limited long-term thermal and mechanical stability are considered as the main challenges that limit the employment of IL/polymer composite membranes in PEMFCs, especially for high-temperature applications.

“…However, reducing the Nafion's conductivity at high-temperature conditions has led to the Nafion-based membrane modification using IL to improve its properties. Zanchet et al 74 studied three types of ILs in fabricating a Nafion/IL blend membrane. The ILs contained the same cation, namely, 3-triethylammonium propane sulfonic ([TEA-PS]), and the anions were [HSO 4 ], [BF 4 ] and [TfO].…”

Ionic liquids (ILs) are promising solvents for catalytic and electrolyte applications, gas absorption, and extractions in electrochemical systems due to their useful features, such as high conductivity and good thermal, chemical, and electrical stability. This review focuses on incorporating ILs into fuel cell (FC) systems, specifically into two main components of FC (ie, polymer electrolyte membrane and electrocatalyst). In FC, a polymer electrolyte membrane with excellent conductivity and deprived of humidity even at high temperatures must be created for effective early commercialization of this technology.Electrocatalyst performance can also be enhanced with additive materials, such as ILs, thus further improving the entire achievement of FCs. This work discusses the most important reasons for ongoing studies and outlines the current progress in using ILs as a revolutionary form of polymer electrolyte membrane and electrocatalyst.

“…(4) The poor crystalline structural characteristics of such membranes make it impossible to deeply analyse and study the proton conductive mechanism, which limits the demand for improving the proton conductivity. 6,7 Therefore, the development of new and inexpensive proton-conducting materials with excellent performance has been a subject of intensive research.…”
