“…Because of its appealing properties, MC is promising to be developed into a host polymer as a matrix for biopolymer electrolyte membranes [44][45]. Some works used MC as a host polymer and/or blend/composite agent, for example MC-NH4NO3-PEG for fuel cell application [36], sulfonated poly(ether ether ketone) with methyl cellulose (SPEEK-MC) for proton exchange membrane [46], methyl cellulose/keratin hydrolysate composite membranes for composite membranes [31] and PE/MC blend microporous membranes as separator in lithium-ion batteries [47].…”

Summary This study discusses three conductive materials—carbon nanotube, graphene oxide, and montmorillonite which recently being used as fillers in membranes of fuel cell application and commonly hybridized with polymers as the matrix. The polymer electrolyte membrane fuel cell (PEMFC) is using a polymer‐based membrane as the electrolyte, which might require filler or functionalization to enhance their cell performance. This review provides brief information for the researcher who insists on improving the current PEM using these potential fillers, specified with required values of membrane properties measurement. It also entails the special features of the nanofillers concerning their chemical structure and electrochemical properties based on recent studies. As electricity is generated from an external fuel source, the membranes that are used should be more than 0.1 S/cm of proton conductivity, low fuel permeability (< 1.37 x 10−6 cm2/s), cheap, and high stability in dry and wet condition. PEM is widely being utilized together with filler(s) incorporated as a purpose to overcome recent drawbacks encountered by the commercial Nafion membrane solely. Hence, the fillers embedded in the membrane are necessarily to have the promising characteristics, acknowledging the potential performances of three conductive nanofillers of (a) carbon nanotubes which is well‐known of its electrical conducting potential with three cylindrical design, (b) graphene oxide which is a reactive carbonaceous material with its multifunctional groups and (c) montmorillonite which is one of the clay types that has tetrahedral and octahedral layers of alumina‐silicates for producing better hybrid polymer electrolyte membrane. Highlights Carbon nanotube, graphene oxide, and montmorillonite are highly promising conductive fillers with outstanding cell performances based on previous studies. Carbon nanotube, graphene oxide, and montmorillonite are chosen as incorporated fillers recently due to their rolling up direction (chirality vector of graphene sheet), reactive functional groups attached on the carbon atoms and ionic multilayers of the tetrahedral and octahedral sheet, respectively. High proton conductivity, low electronic conductivity, low fuel permeability, low water transport, low production cost, and high mechanical stability in both dry and wet condition are properties that should be portrayed by a good hybrid membrane.

“…Aromatic hydrocarbon polymers such as polyimides (PIs), poly(ether ether ketone)s (PEEKs), and poly(arylene ether sulfone)s (PAESs) show high inherent stability, high glass transition, and low cost, as a result they are attractive alternatives which are expected to replace Nafion. Usually, these polymers are sulfonated by chlorosulfonic acid, fuming sulfuric or other strong sulfonating agent.…”

Sulfonated titanium dioxide (STiO 2 ) was prepared by the reaction of TiO 2 with 1,3-propanesultone. Novel STiO 2 incorporated sulfonated poly(aryl ether sulfone) (SPAES) nanocomposite proton exchange membranes (PEMs) were made by solution casting. Fourier transform infrared, X-ray photoelectron spectroscopy, and proton nuclear magnetic resonance indicated the successful preparation of STiO 2 and SPAES. The thermogravimetric analysis and oxidative stability testing results implied that SPAES/STiO 2 membranes had better stability than pristine SPAES membrane. Meanwhile, the scanning electron microscopy spectra exhibited that the introduction of sulfonated groups on the surface of TiO 2 significantly improved its dispersibility in SPAES matrix. More specifically, SPAES membrane incorporated with 2%STiO 2 exhibited higher proton conductivity (60 mS cm −1 ), lower methanol permeability (2.1 × 10 −7 cm 2 s −1 ) and better proton selectivity (28.0 × 10 4 S s cm −3 ) than that of pure SPAES and SPAES/1%TiO 2 membrane. The SPAES-1%STiO 2 membrane showed better performance in direct methanol fuel cell (DMFC) test than SPAES and Nafion 117 due to the reduction of methanol crossover. From these results, it is evident that SPAES/STiO 2 nanocomposite PEMs have great potential for applications in DMFCs.
