Novel PVA/La2Ce2O7 hybrid nanocomposite membranes for application in proton exchange membrane fuel cells
Proton exchange membrane fuel cells (PEMFCs) are electrochemical devices that show the highest power densities compared to the other type of fuel cell. In this work, nanocomposite membranes used for proton exchange membrane fuel cells as poly(vinyl alcohol)/La2Ce2O7 (PVA-LC) with the aim of increasing the water uptake and proton conductivity. Glutaraldehyde (GA) was used as cross linking agent ...
متن کاملTowards neat methanol operation of direct methanol fuel cells: a novel self-assembled proton exchange membrane.
We report here a novel proton exchange membrane with remarkably high methanol-permeation resistivity and excellent proton conductivity enabled by carefully designed self-assembled ionic conductive channels. A direct methanol fuel cell utilizing the membrane performs well with a 20 M methanol solution, very close to the concentration of neat methanol.
متن کاملSilicon-based Proton Exchange Membrane for Micro Direct Methanol Fuel Cells
This paper presents our research on silicon-based proton exchange membranes for siliconbased micro fuel cell applications. The porous silicon membranes with a thickness of 20-40 m were fabricated. And the porous silicon-based proton exchange membranes were formed by using the combination of the porous silicon membranes and Nafion solution. The proton conductivities of the porous silicon-based P...

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-...
