“…During the DMFC operation, anions transported through the PEMs from the cathode to the anode and generated H 2 O 2 as an intermediate product along with hydrogen and water. This intermediate free radical might degrade the PEMs 42 . The chemical stability of the Mindel composite PEMs was assessed by Fenton's test and shown in Table 3.…”

Sulfonated polyethersulfone (SPES), polyaniline (PANI), and Cloisite 15 A ® were used as modifiers for the fabrication of Mindel composite polymer electrolyte membranes (PEMs). Pristine Mindel and Mindel composite PEMs were fabricated by the solution intercalation technique. The presence of modifiers in the Mindel membrane matrix was confirmed by Fourier transform infrared (FTIR) studies. The primary characteristics of pristine Mindel and Mindel PEMs such as water uptake, methanol uptake, proton conductivity ion-exchange capacity (IEC), and chemical and mechanical stability were evaluated. The pore size of Mindel/SPES/Cloisite 15 composite PEM was increased owing to the addition of SPES and Cloisite 15. The higher proton conductivity of 4.323 × 10 −4 S cm −1 , enhanced IEC of 0.482 mequiv. g −1 , and maximum water uptake (%) of 38.12 were noted for Mindel/SPES/Cloisite membrane. Membrane selectivity of all Mindel PEMs was enhanced by the addition of modifiers. The results of this study indicate that Mindel composite membranes could be utilized as PEMs for direct methanol fuel cell (DMFC).

“…The swelling characteristics were evaluated by measuring the difference in the dimension of the membrane samples, as reported in the literature 39 . The dimensions of membrane samples in dry and wet condition was recorded, and the swelling ratio was estimated using the following equation,

Swelling ratio (() %) = \frac{T_{wet} - T_{dry}}{{normalT}_{italicdry}} \times 100

where T wet = length of wet membrane, and T dry = length of the dry membrane.…”

Proton exchange membrane fuel cell (PEMFC) is a promising technology that offers a clean and efficient renewable energy source. The hybrid SiO2, sulfonated SiO2 (SSiO2), and metal–organic framework‐5 (MOF‐5) incorporated sulfonated poly (ether ether ketone) (SPEEK) ternary composite membranes are fabricated using dry phase inversion technique for PEMFC. The membrane performance is evaluated in terms of water uptake, ion exchange capacity, methanol permeability, and proton conductivity (PC) measurements. The morphological study of fabricated membranes was carried out using scanning electron microscopy and atomic force microscopy analysis. The mechanical stability is strengthened up to 30–40%, and the PC gets enhanced with the incorporation of MOF‐5, achieving simultaneous improvement in proton conduction and membrane stability. The PC of the ternary SPEEK/SSiO2/MOF‐5 membrane is 3.69 × 10−3 S cm−1, 32% more than the neat membrane. A significant increase in selectivity of 23% is observed by incorporating SSiO2 and MOF‐5 fillers when compared with the neat membrane. The synergistic effect of MOF‐5 and SSiO2 in the ternary membrane has significantly improved water retention and proton conductivity. The functional SO3H groups of SiO2 and MOF‐5 bonded via acid–base electrostatic interactions with the SPEEK; enhances proton conduction accompanied by suppressing the methanol penetration through membranes.

The facile fabrication of proton exchange membrane (PEM) by intermixing of aminoethylpiperazine monomer (AEP), diamino diphenylmethane (DDM) monomer, and AEP combine with varying compositions of DDM (2, 4, and 6 wt%) copolymer with sulfonated polyethersulfone (SPES) and polyamide‐imide (PAI) polymer matrix for fuel cell applications. The intermixing of AEP@DDM copolymer in the SPES/PAI matrix was confirmed by Fourier transform infrared spectroscopy (FTIR) and X‐ray diffraction spectroscopy (XRD) techniques. The physicochemical performance of fabricated PEM was analyzed by water uptake, ion exchange capacity (IEC), swelling ratio, thermal degradation, hydrolytic degradation, chemical and mechanical properties. The intermixing copolymer (AEP@DDM) has significantly suppressed the thermal and hydrolytic deterioration of the PEM. Furthermore, the PAI had noteworthy to improve the thermal and chemical stability of the membranes significantly. The proton conductivity of the SPES/PAI/AEP@DDM (6%) membrane was found to be 5.68 × 10−4 S cm−1 which is 104% higher than the pristine SPES membrane. Besides, the selectivity of SPES/PAI/DDM (6%) was also enhanced up to 80.34% compared to pristine SPES membrane. The inclusion of AEP@DDM in SPES/PAI enhanced the proton conductivity and contributed to the membrane structure's uniformity, as revealed from morphological studies. The AEP@DDM copolymer modification of SPES/PAI membrane has shown good stability, physicochemical property and can be considered as a promising membrane material for fuel cell application.
