“…Intercalation of CeZnO x in the polymer matrix inhibits the movement and expansion of the SPPO chain and decreases the SR of the membranes. 55 As a result, SPZ-0 exhibits the highest SR (10%) compared to the composite PEMs. It is worth noting that higher WU and low SR of the composite PEMs enhance their suitability for PEMFC applications.…”

The incorporation of cerium−zinc bimetallic oxide (CeZnO x ) nanostructures in sulfonated poly(2,6-dimethyl-1,4phenylene oxide) (SPPO) membranes holds promise in an enhanced and durable fuel cell performance. This investigation delves into the durability and efficiency of SPPO membranes intercalated with CeZnO x nanostructures by varying the filler loading of 1, 2, and 3% (w/w). The successful synthesis of CeZnO x nanostructures by the alkali-aided deposition method is confirmed by wideangle X-ray diffraction spectroscopy (WAXS), Raman spectroscopy, field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS) analyses. CeZnO x @SPPO nanocomposite membranes are fabricated using a solution casting method. The intricate interplay of interfacial adhesion and coupling configuration between three-dimensional CeZnO x and sulfonic moieties of the SPPO backbone yields an enhancement in the bound water content within the proton exchange membranes (PEMs). This constructs simultaneously an extensive hydrogen bonding network intertwined with the proton transport channels, thereby elevating the proton conductivity (K m ). The orchestrated reversible redox cycling involving Ce 3+ /Ce 4+ enhances the quenching of aggressive radicals, aided by Zn 2+ , promoting oxygen deficiency and Ce 3+ concentration. This synergistic efficacy ultimately translates into composite PEMs characterized by a mere 4% mass loss and a nominal 6% decrease in K m after rigorous exposure to Fenton's solution. Remarkably, an improved power density of 403.2 mW/cm 2 and a maximum current density of 1260.6 mA/cm 2 were achieved with 2% loading of CeZnO x (SPZ-2) at 75 °C and 100% RH. The fuel cell performance of SPZ-2 is 74% higher than its corresponding pristine SPPO membrane.

“…Composite cross-linked GO membranes have also attained much consideration as a highly suitable PEM with improved physiochemical and electrochemical properties. The poly(acrylonitrile)- co -poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAN- co -PAMPS) composite with different contents of GO have shown improved structural, morphological, thermal, and mechanical properties . The composite membrane was able to enhance the ionic conductivity (5.43 × 10 –2 S cm –1 ) without an increase in water uptake as a result of the interaction of sulfonic acid of the polymer with hydrophilic functionalities of GO with the fuel cell performance of 416.6 mW cm –2 under H 2 /O 2 conditions .…”

Graphene oxide (GO), a single sheet of graphite oxide, has shown its potential applications in electrochemical energy storage and conversion devices as a result of its remarkable properties, such as large surface area, appropriate mechanical stability, and tunability of electrical as well as optical properties. Furthermore, the presence of hydrophilic functionalities on basal and edge planes induces other relevant properties, which make GO an attractive material for electrochemical applications. On account of having structural diversity and enhanced overall crucial properties, GO and its composites have attracted much attention in contribution of energy storage devices, such as batteries, supercapacitors, and energy conversion devices, such as fuel cells and water electrolyzers. Previous review reports demonstrated the individual applications of GO or reduced graphene oxide (RGO) in either of the electrochemical energy devices. The present review highlights all of the recent developments of GO and RGO in both the energy storage and conversion devices along with the recent synthesis methodologies, which are crucial to unveil all of the outperforming properties of GO and RGO. The transition in the synthesis of GO with various chemical methods, including the Brodie and improved Hummers methods, to electrochemical approaches have been described with recent developments as well as highlights of the importance of electrochemical energy in the synthesis of GO. Utilization of GO in energy storage applications predominantly as electrodes and electrolytes and membranes in energy conversion devices further diversify its multiple applicability as a result of its variable functional properties. Multiple energy storage devices, such as Li-ion, Na-ion, Li−S, and flow batteries and supercapacitors, have shown the enhanced performance with the introduction of GO and RGO. Furthermore, GO has also shown excellent applicability in energy conversion devices, such as protonexchange membrane fuel cells, methanol fuel cells, and water electrolyzers, which have also been discussed in this review. This review further summarizes the recent synthesis methodologies of GO and RGO along with their importance in electrochemical energy devices with allied challenges and future perspectives.

Fuel cells are the most promising alternative green and clean energy source in the future because of their low carbon emissions. Fuel cells have been employed in various applications, including large-scale stationary power generation, distributed combination heat and power, transport, and mobile and stationary applications. Generally, a fuel cell system consists of a proton exchange membrane or polymer electrolyte membrane (PEM), a catalyst layer, a microporous layer, a gas diffusion layer, and a bipolar plate at the anode and cathode. PEMs are an important component in fuel cell applications that act as proton carriers and separators for the anode and cathode, while catalyst support materials are a major component of proton exchange membrane fuel cell. The membrane and catalyst affect the cost, durability, and electrochemical activity of fuel cells. Researchers have made serious attempts to develop materials that can reduce the cost of membrane and catalyst manufacturing, lowering the overall cost of fuel cells. Because of its unique features like 2D structure, ease of fabrication, and low production cost, graphitic carbon nitride (g-CN or g-C 3 N 4 ) is now frequently mentioned.Due to their exceptional qualities, carbon-based materials are also commonly used in a variety of applications, including fuel cells. The effectiveness of experiments using g-C 3 N 4 , carbon nanotube (CNT), and graphene as essential materials in enhancing fuel cell performance is discussed in this study. This review, primarily for fuel cell applications, discusses ways of adjusting the structure in terms of porosity, dimension tailoring, and atomic and edge functionalization. The study also involved the properties of composite materials as well as their respective applications on membranes as well as fuel cell catalysts. This review is useful for investigations into g-C 3 N 4 , CNT, and graphene because it offers ideas and direction for improving the potential of associated systems, including fuel cells, hydrogen production, solar cells, batteries, and supercapacitors.Abbreviations: CHP, combination heat and power; CNT, carbon nanotube; DMFC, direct methanol fuel cell; g-CN or g-C 3 N 4 , graphitic carbon nitride; MEA, membrane electrolyte assembly; ORR, oxygen reduction reaction; PEM, polymer electrolyte membrane; PEMFC, proton exchange membrane fuel cell; SPEEK, sulfonated poly (ether ether ketone).
