Proton and Methanol Transport in Poly(perfluorosulfonate) Membranes Containing Cs + and H + Cations
Open accessAbstract
Poly(perfluorosulfonate acid) membranes were doped with cesium ions to several degrees. These, along with the ‐form membrane, were investigated in relation to methanol permeability as well as hydrogen ion conductivity. While retaining considerable conductivity, the cesium‐doped membranes are highly impermeable to methanol. We found that methanol permeability in the membrane reduced by over one order of magnitude, owing to the presence of cesium ions. These findings are discussed on the basis of alterations produced by cesium in the membrane microstructure. Also discussed is the potential implication of these results in the direct methanol fuel cell technology.

In modified Nafion membranes, there was always a significant loss in proton conductivity when methanol permeability was reduced.

Mechanistic Studies of CO2 Reduction on a Mediated Electrode with Conducting Polymer and Inorganic Conductor Films K. Ogura,* N. Endo, and M. Nakayama Department of Applied Chemistry, Yamaguchi University, Ube 755-8611, Japan ABSTRACT Electrocatalytic reduction of CO2 on a metal complex-immobilized polyaniline (PAn)/Prussian blue (PB)-laminated electrode has been investigated by means of long-term electrolysis, liquid chromatography/mass spectroscopy (LC/MS) and in situ Fourier transform infrared (FTIR) reflection absorption spectroscopy. The major products were lactic, acetic, and formic acids, methanol, and ethanol. The roles of PAn and the metal complex [1,8-dihydroxynaphthalene-3,6-disul- fonatoferrate(II)] are to render CO2 chemically active by combining the electrophilic carbon atom with the amino group of PAn and the basic oxygen atom with the central metal of the complex, and that of PB is to provide catalytically H atoms on its zeolitic lattice. The activated CO2 is hydrogenated and converted to organic acids and alcohols by the reac- tion with Had, atoms. It is suggested that formaldehyde is a precursor for the organic acids (except formic acid) and alco- hols and the insertion reactions of CO2 into intermediates are essential to the formation of C2 and C3 compounds.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
