State of Water in Perfluorosulfonic Ionomer (Nafion) Proton Exchange Membranes
This manuscript reports on the direct identification of four states of water in hydrated Nafion ionomer polymers, including a quantitative measurement of their dynamics, as previously published in the Journal of the Electrochemical Society, 155, B163-B171 (2008). Here, we provide further details on the dynamics of these water states and we underline still-open scientific questions, towards stim...
متن کاملWater Soluble Polymers as Proton Exchange Membranes for Fuel Cells
The relentless increase in the demand for useable power from energy-hungry economies continues to drive energy-material related research. Fuel cells, as a future potential power source that provide clean-at-the-point-of-use power offer many advantages such as high efficiency, high energy density, quiet operation, and environmental friendliness. Critical to the operation of the fuel cell is the ...
متن کاملMethanol crossover and selectivity of nafion/heteropolyacid/montmorillonite nanocomposite proton exchange membranes for DMFC applications
In this work, we prepared the nafion/montmorillonite/heteropolyacid nanocomposite membranes for direct methanol fuel cells (DMFCs). The analyses such as X-ray diffraction (XRD), Fourier transform infrared (FTIR), and scanning electron microscopy (SEM) were conducted to characterize the filler dispersion and membrane structure in prepared nanocomposite membranes. XRD patterns of nafion-CsPW-MMT ...
متن کاملNovel 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 کاملInvestigations of Conductivity in FEP-Based Radiation-Grafted Alkaline Anion-Exchange Membranes
A series of radiation-grafted alkaline anion-exchange membranes (AAEMs) with degrees of grafting (by mass) in the range 20 – 26% were produced and characterised. Conductivities (from impedance spectroscopy) up to 0.023 ± 0.001 S cm at 50 ± 1°C were demonstrated, which are between 20 – 50% of values for the commercial acidform membrane Nafion-115 (σ = 0.045 ± 0.004 (65°C) – 0.104 ± 0.008 (50 ± 1...
