“…13 Chitosan (CS) is an ecofriendly polymer consisting of b-(1,4)linked 2-amino-deoxy-D-glucopyranose; 14 it can be used in various fields, including the pharmaceutical, cosmetics, biomedical, gas-separation, wound-healing, and food industries. [15][16][17] CS contains a large quantity of -NH 2 and -OH groups, which chelate many heavy-metal ions; thus, they offer improved adsorption capabilities and selectivity. In addition, the hydrophilic nature of CS makes it more suitable than Nafion for use at high temperatures and in relatively humid environments.…”

In this study, we incorporated commercially available p‐toluene sulfonic acid coated boehmite nanofillers (commercially known as OS1) into the chitosan (CS) matrix to fabricate CS–OS1 nanocomposite membranes with a high proton conductivity for fuel‐cell applications. These nanocomposite membranes were characterized by Fourier transform infrared spectroscopy, energy‐dispersive X‐ray spectroscopy, X‐ray diffraction analysis, scanning electron microscopy, and thermogravimetric analysis. Their mechanical properties, water uptake, ion‐exchange capacity, and proton conductivity were also determined. The results show that the incorporation of OS1 to CS chains can inhibit the mobility of CS chains and, hence, enhance the thermal stability and mechanical properties of CS–OS1 nanocomposite membranes. The composite membrane with 5 wt % OS1 showed a proton conductivity of 0.032 S/cm; this was almost equal to that of commercially available Nafion 117. We concluded that CS–OS1 nanocomposite membranes have potential for fuel‐cell applications. © 2018 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2019, 136, 46904.

“…In recent decades, extensive research on the development of high‐performance fuel cells has been done in order to generate and store energy at low cost. Cost‐effective and enviromentally friendly PEMs prepared from natural polymers will become a promising substitute for currently used synthetic polymers such as Nafion and sulfonated engineering polymers …”

“…Cost-effective and enviromentally friendly PEMs prepared from natural polymers will become a promising substitute for currently used synthetic polymers such as Nafion and sulfonated engineering polymers. [1][2][3] Chitosan (CS) is the partially deacetylated polysaccharide of chitin that is the principal component of living organisms such as fungi and crustaceans. It has attracted more attention because it has excellent biocompatibility and biodegradability, high hydrophilicity, low methanol permeability, and easy chemical functionalization.…”

Titania‐coated carbon nanotubes (TCNTs) were obtained by a simple sol–gel method. Then chitosan/TCNT (CS/TCNT) composite membranes were prepared by stirring chitosan/acetic acid and a TCNT/ethanol suspension. The morphology, thermal and oxidative stabilities, water uptake and proton conductivity, and mechanical properties of CS/TCNT composite membranes were investigated. The CNTs coated with an insulated and hydrophilic titania layer eliminated the risk of electronic short‐circuiting. Moreover, the titania layer enhanced the interaction between TCNTs and chitosan to ensure the homogenous dispersion of TCNTs in the chitosan matrix. The water uptake of CS/TCNT composite membranes was reduced owing to the decrease of the effective number of the NH2 functional groups of chitosan. However, the CS/TCNT composite membranes exhibited better performance than a pure CS membrane in thermal and oxidative stability, proton conductivity, and mechanical properties. These results suggest that CS/TCNT composite membranes are promising materials for new proton‐exchange membranes. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016, 133, 43365.

“…Schematic representation of a PEMFC is shown in Figure 5. There are two types of proton exchange membrane fuel cells, namely: hydrogen fuel cells and direct methanol fuel cells (DMFC), both of which utilize proton exchange membrane to transfer protons [13]. In hydrogen fuel cells at the anode, hydrogen is oxidized to liberate two electrons and two protons [24].…”

Fuel cells are electrochemical devices which convert chemical energy into electrical energy. Fuel cells have attracted attention due to their potential as a promising alternative to traditional power sources. More recently, efficient and environmentally benign biopolymer "chitosan" have been extensively investigated as a novel material for its application in fuel cells. This biopolymer can be used in both membrane electrolyte and electrode in various fuel cells such as alkaline polymer electrolyte fuel cells, direct methanol fuel cells and biofuel cells. This review provides an overview of main available fuel cells following by application of chitosan as novel biopolymer in fuel cells technology. Recent achievements are included and recommendations are also given for areas of future research.
