Selectivity of Direct Methanol Fuel Cell Membranes
Sulfonic acid-functionalized polymer electrolyte membranes alternative to Nafion(®) were developed. These were hydrocarbon systems, such as blend sulfonated polyetheretherketone (s-PEEK), new generation perfluorosulfonic acid (PFSA) systems, and composite zirconium phosphate-PFSA polymers. The membranes varied in terms of composition, equivalent weight, thickness, and filler and were investigat...

متن کاملCharacterization of Polyethylene-Graft-Sulfonated Polyarylsulfone Proton Exchange Membranes for Direct Methanol Fuel Cell Applications
This paper examines polymer film morphology and several important properties of polyethylene-graft-sulfonated polyarylene ether sulfone (PE-g-s-PAES) proton exchange membranes (PEMs) for direct methanol fuel cell applications. Due to the extreme surface energy differences between a semi-crystalline and hydrophobic PE backbone and several amorphous and hydrophilic s-PAES side chains, the PE-g-s-...
متن کاملDirect Methanol Fuel Cell Thermodynamic Simulation
The direct methanol fuel cell (DMFC) is considered a viable power production technology for portable electronics equipment (10’s-100’s watts) and transportation vehicles (10’s-100’s kilowatts). Since methanol is relatively inexpensive and a reformer or other fuel processing equipment is not required for the DMFC, this power system has the potential to be low cost, compact, reliable and fuel eff...
متن کاملFabrication of Nanocomposite Membrane via Combined Electrospinning and Casting Technique for Direct Methanol Fuel Cell
Emergence of nanotechnology has resulted in the introduction of the electrospinning process in fabricating and characterising the polymer electrolyte membrane from the sulfonated poly (ether ether ketone) (SPEEK) nanocomposite membrane comprised of electrospun Cloisite15A® (e-spun CL...
