The application of organic-inorganic nanocomposite membranes allows for a synergy between the desirable thermal and mechanical properties inorganic materials with reactivity, dielectric properties, durability, flexibility, processability polymeric materials. Proton exchange membrane fuel cells (PEMFCs) suffer from some problems including water content management, carbon monoxide poisoning, hydr...

In this paper, the silicon-containing sulfonated polystyrene/acrylate–ionic liquid (Si-SPS/A–IL)hybrid membranes was prepared to obtain the proton exchange membrane (PEM) materials withhigh methanol barrier and good selectivity. The Si-SPS/A–IL hybrid membranes characterized asthe function of IL to evaluate their potential as PEMs in direct methanol fuel cells (DMFCs).Fourdifferent Hybrid mater...

In this work, new doped Nafion membranes for PEMFC are prepared by casting with 1 wt% loading of the indazole- and condensed pyrazolebisphosphonic acids (AzBPs). The were analysed ATR-FTIR spectroscopy their morphology was examined SEM. Membranes evaluated water uptake ion exchange capacity (IEC), hydration number estimated. proton conduction properties modified electrochemical impedance (EIS),...

Proton exchange membranes (PEM) for a direct methanol fuel cell (DMFC) have main drawbacks which are methanol permeability, reduced proton conductivity and the cost of the membrane. This paper reviews different polymeric materials such as fluorinated, non-fluorinated, acid-base complex, and composite membranes for DMFC. Currently, nonfluorinated membranes gain a lot of atte...
