“…Moreover, cerium oxide nanoparticles [32], [33] have been used to remove peroxide radicals that are formed during fuel cell operation to improve durability and lifetime. Furthermore, the filler materials incorporated into the nafion polymer matrix can also be functionalised providing improved, or completely new properties, for example, increased proton conductivity via sulphonation [31], [34], [35], [36]. The work on inorganic fillers has been extensively reviewed by Bakangura et al [37].…”

Increasing Polymer Electrolyte Fuel Cells' (PEFCs) operating temperature has benefits on the performance and the ease of utilisation of the heat generated; however, efforts for high temperature PEFCs have resulted in high degradation and reduced life time. In the literature, conventional low temperature (T<80°C) and high temperature (140-200°C) regimes have been extensively studied, while the gap of operating at intermediate temperature (IT) (100-120°C) has been scarcely explored. The main bottleneck for operating at IT conditions is the development of a suitable proton exchange membrane with comparable performance and lifetime to the commercially used Nafion operating at conventional conditions. In this work, composite membranes of Graphene Oxide (GO) and Nafion of varied thickness were fabricated, characterised and assessed for in-situ single cell performance under automotive operating conditions at conventional and intermediate temperatures. The material characterisation confirmed that a composite GO-Nafion structure was achieved. The composite membrane demonstrated higher mechanical strength, enhanced water uptake, and higher performance. It was demonstrated that by utilising GO-Nafion composite membranes, an up to 20% increase in the maximum power density at all operating temperatures can be achieved, with the optimum performance is obtained at 100°C. Moreover, the GO-Nafion membrane was able to maintain its open circuit voltage values at increased temperature and reduced thickness, indicating better durability and potentially higher lifetime.

“…There were also studies on other polymers that have good conductivity improved after incorporating GO together. Li et al 158 investigated the performance of sulfonated GO incorporated onto SPEEK as a highly potential PEM with a sandwich‐alike composite looking. This research claimed SPEEK/SGO/SPEEK membrane was a promising hybrid PEM in semi‐passive DMFC attributed to its higher ionic exchange capacity (2.17 ± 0.02 meq/g), lower methanol permeability ([2.60 ± 0.13] × 10 6 cm 2 /s at 25°C), higher electrochemical selectivity (3.57 × 10 4 S s/cm 3 at 65°C) and 60% higher of peak power density (140.5 ± 1.4 mS/cm at 80°C) than the commercial Nafion 112 membrane.…”

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.

“…In particular, a significant improvement in the electrocatalytic activity of electrodes was observed with graphene or modified graphene as the catalyst support or as a metal-free catalyst (Iwan et al, 2015;Morales-Acosta et al, 2019). Moreover, the incorporation of graphene oxide (GO) or sulfonated graphene oxide (SGO) into a polymer matrix of the PEM (Li et al, 2017;Pandey et al, 2017;Qiu et al, 2017) enhance its ionic conductivity and improve its physicochemical properties (Beydaghi et al, 2014).…”
