“…The solubility in water was reduced, and a high proton conductivity was attained for the cross‐linked membrane. Dang applied a covalent cross‐linking process on poly(arylene ether ketone)s (cPAEKs) using N ‐hydroxysuccinimide as the cross‐linking agent. The resulting membrane exhibited a 15% improvement in the cross‐link process and performed with low methanol permeability, high thermal stability, and high mechanical strength.…”

Summary Additives such as fillers, cross‐linkers, and plasticizers have become increasingly important in the polymer nanocomposite production field, especially for enhancing the structural morphology, functional behavior, and final performance of nanocomposites in broad applications. The current work is an overview of the effects of additive substances such as fillers, cross‐linkers, and plasticizers in the polymer electrolyte membrane composites applied to fuel cells. A comparative review is conducted by categorizing fillers into several types, and the most popular cross‐linkers and plasticizers used in fuel cell membranes are included in this review. The highlighted properties include the proton conductivity, permeability, mechanical properties, thermal properties, crystallinity, and structure of additive‐modified nanocomposites. Furthermore, the challenges and future prospects in the additive field are discussed in Section 5.0. This review can provide a reference for researchers seeking specific substances that can be used to enhance nanocomposite properties, especially in membrane fuel cell applications.

“…Sulfonated polyether ether ketone (SPEEK) is an inexpensive polymer electrolyte and it possesses satisfactory mechanical properties, thermal properties and good chemical stability. 5,6 However, the proton conductivity of SPEEK membranes mainly depends on water content, and limits high temperature fuel cell operation. Incorporation of nanosized inorganic ller materials into the polymer matrix can inuence the properties of the parent polymer, such as proton conductivity, mechanical and thermal stability.…”

Sulfonated polyether ether ketonesulfonated graphene oxide composite membranes for polymer electrolyte fuel cells have been prepared. Sulfonic acid functionalised graphene oxide nanosheets were incorporated into the sulfonated polyether ether ketone structure to interconnect the proton transport channels. The composite membranes were characterised by SEM, which revealed a uniform distribution of nanosheets into the polymer structure. FTIR showed the chemical interactions of functionalised graphene oxide with SPEEK membranes. Proton conductivity of the composite membrane was measured at various temperatures and relative humidities; the SGO/SPEEK composite membrane showed a very good conductivity of 0.055 S cm À1 at 80 C and 30% RH, which was greater than that of recast SPEEK which was about 0.015 S cm À1 . The fuel cell performance of SGO/SPEEK at 80 C and 30% RH was 378 mW cm À2 , which was higher than that of recast SPEEK.
