High-temperature proton-exchange membrane fuel cells (HT-PEMFCs) have indeed emerged as highly efficient devices for energy conversion with numerous applications, ranging from portable electronics to transportation. The development of advanced electrolyte materials is imperative to enhance the PEMFCs' stability and performance. Herein, we use sulfonated polyvinyl chloride (SPVC) and 2,5-benzimidazole-modified montmorillonite (AB-MMT) to create a series of novel composite electrolytes for PEMFC via a solution-casting method. PVC, well known for its excellent film-forming properties, is combined with modified MMT, a natural inorganic clay with a high surface area and ion-exchange capability (IEC). The composite polymer electrolyte membranes (PEMs) are further doped with phosphoric acid (PA) at varying concentrations. The structural, morphological, and electrochemical properties of prepared PEMs are systematically analyzed using FTIR, XRD, SEM, and impedance spectroscopies. The effect of PA on PEMs in terms of water uptake, mechanical and chemical stability, and ionic conductivity is also analyzed. The synergy between SPVC and AB-MMT creates a favorable microenvironment for ion transport within the membrane, contributing to enhanced PEMFC performance. The experimental results demonstrate that 10SBZMP exhibits a substantial increase in ionic conductivity, i.e., 0.069 at 150 °C and RH 98% with a power density of 0.252 W/cm 2 . The development of advanced materials like these paves the way for more efficient and reliable fuel-cell technologies, contributing to the sustainable energy landscape of the future.

“…Concretamente, la utilización de arcillas tipo Montmorillonita (MMT) como refuerzo mecánico [11]- [13] para la obtención de nanocompositos poliméricos, son consideradas una buena opción, debido a que este mineral cuenta con características de rigidez, flexibilidad, resistencia y estabilidad dimensional necesarias como para mejorar las propiedades del material final [14], [15]. Estructuralmente las MMT están conformadas por láminas, dónde cada lámina a su vez consta de tres capas unidas: dos capas de sílice tetraédricas y en el medio de ellas una capa de alúmina octaédrica.…”

En el presente trabajo se obtuvieron películas termoplásticas de almidón yuca por medio del proceso de gelatinización del almidón. La formulación base (BPG), es decir la matriz se realizó con 30% en peso de glicerina, la cual posteriormente fue reforzada con tres porcentajes de arcilla Montmorillonia K10 diferentes (MMT): 3%, 5% y 10%, denominadas BPGK-3%, BPGK-5% y BPGK-10%, respectivamente. Se midieron las propiedades mecánicas y se visualizó por microscopia óptica todas las películas de las cuatros formulaciones, en donde la formulación que obtuvo las mejores propiedades mecánicas fue la formulación BPGK-5%, debido a la distribución de las partículas de la arcilla en la matriz termoplástica.

Solid polymer electrolytes (SPEs) are desirable for next‐generation lithium‐ion batteries due to their flexibility, processability, and increased safety. However, limited ionic conductivity in solid polymer electrolytes (SPEs) restricts lithium‐ion transport, hindering battery performance. Composite polymer electrolytes (CPEs) emerge as a potential solution by addressing this limitation. A novel CPE with enhanced ionic conductivity and electrochemical stability is developed in this work to overcome this difficulty. The novel electrolytes are synthesized by incorporation of prepared nickel oxide (NiO) and cobalt oxide (Co3O4) nanofillers at varying weight percentages (0%, 5%, 10%, 15%, and 20%) into a PVDF‐HFP/PMMA/LiClO4/EC polymer blend using a solution casting technique. X‐ray diffraction and Fourier transform infrared spectroscopy (FTIR) confirm the effective incorporation of the fillers into the blend by assessing the structure of the polymer electrolyte. The optimal composition, containing 15 wt% each of NiO and Co3O4, exhibited a high ionic conductivity of 10−3 S/cm and an electrochemical stability window of 4.5 V at room temperature. Scanning electron microscopy (SEM) analysis revealed a porous structure with a smooth surface in the Li‐ion conducting blend, facilitating faster ion movement. The enhanced Li‐ion transportation, improved mechanical and thermal properties, and fire‐retardant characteristics make these CPEs promising candidates for energy storage devices.Highlights A novel PVDF‐HFP based polymer electrolyte is prepared for LIB application. Amalgamation of NiO and Co3O4 nanofillers enhanced electrochemical performance. The PEs conductivity (⁓10−3 S/cm) is sufficient for implementation in LIBs. Synthesized PEs can be a potential alternative for the conventional PEs.
