“…This improves the class of cellulose composites’ proton conductivity [ 109 ]. The same research group further evaluated the performance of the modification of cellulose materials, where various amounts of 1H-1,2,3 triazole (Tri) were doped in nanocrystalline cellulose (CNC) [ 110 ]. There was no structural change in the cellulose after CNC functionalization with Tri.…”

“…Proton transportation was regulated by triazole ring reorientation, and conductivity performance is compatible with Grotthuss mechanism. Comparing CNC-Tri to CNC treated by imidazole, it was observed that CNC-Tri had improved thermal characteristics [110]. Selyanchyn et al investigated the impact of sulfosuccinic acid (SSA) cross-linking with CNC with different ratios [111].…”

Hydrogen fuel cell (FC) technologies are being worked on as a possible replacement for fossil fuels because they produce a lot of energy and do not pollute the air. In FC, ion-exchange membranes (IEMs) are the vital components for ion transport between two porous electrodes. However, the high production cost of commercialized membranes limits their benefits. Various research has focused on cellulose-based membranes such as IEM with high proton conductivity, and mechanical, chemical, and thermal stabilities to replace the high cost of synthetic polymer materials. In this review, we focus on and explain the recent progress (from 2018 to 2022) of cellulose-containing hybrid membranes as cation exchange membranes (CEM) and anion exchange membranes (AEM) for proton exchange membrane fuel cells (PEMFC) and alkaline fuel cells (AFC). In this account, we focused primarily on the effect of cellulose materials in various membranes on the functional properties of various polymer membranes. The development of hybrid membranes with cellulose for PEMFC and AFC has been classified based on the combination of other polymers and materials. For PEMFC, the sections are associated with cellulose with Nafion, polyaryletherketone, various polymeric materials, ionic liquid, inorganic fillers, and natural materials. Moreover, the cellulose-containing AEM for AFC has been summarized in detail. Furthermore, this review explains the significance of cellulose and cellulose derivative-modified membranes during fuel cell performance. Notably, this review shows the vital information needed to improve the ion exchange membrane in PEMFC and AFC technologies.

“…A distinctive superiority of MOFs over other fillers is the ability to generate interconnected microporous networks, expedite the conduction of protons, and confine water in hybrid membranes. Imidazole, , triazole, , and pyrazole groups were previously reported to show proton conductivity at low humidity conditions by forming proton-conductive pathways as the N atoms in heterocyclic azoles can act as sites for proton acceptors and transfer them to the next. In several studies, imidazole groups loaded into the pores of MOFs or molecular sieves have been reported that generate materials as solid-state proton conductors.…”

A unique zirconium-based microporous MOF-808 constructed from Zr6 nodes (Zr6O4(OH)4) and BTC (benzene-1,3,5-tricarboxylic acid) synthesized herein has been further tailored by radical in situ polymerization of 1-vinylimidazole alongside N,N′-methylene-bis(acrylamide) as the cross-linker after their adsorption inside MOF pore channels. The cross-linked architectures were incorporated as fillers at 2 and 4 wt % in sulfonated poly (ether ether ketone) (SPEEK) solution to formulate mixed-matrix composite Proton Exchange Membranes (PEMs). The composite membranes displayed considerably higher proton conductivity, improved fuel cell performance, and thermal stability than pristine SPEEK. The highly ordered crystal-controlled 3D polymeric cross-linked networks created in the MOF channels address the undesirable leaching associated with adding low-molecular-weight azoles in membranes. Additionally, it generates highly ordered long-range proton-conducting channels through the MOF pores. The acid–base interaction between the imidazole and sulfonic functional groups causes the conductivity of protons to increase to 0.05 S/cm at 80 °C and 70% RH for the S4P3M membrane containing 4 wt % complex filler, which is 16.6-fold higher than that of pure SPEEK. The membrane retains a proton conductivity of up to 0.04 S/cm at 100 °C and 40% RH, indicating its proton-conducting abilities at low humidity conditions. Furthermore, S4P3M achieves a peak power density of 310 mW/cm2 at 60 °C and 347 mW/cm2 at 80 °C under 70% relative humidity, which are higher than those in several other reported literature studies on SPEEK-based membranes.
