Alkaline imidazolium- and quaternary ammonium-functionalized anion exchange membranes for alkaline fuel cell applications
Abstract
Alkaline imidazolium-type ionic liquids (ILs) and quaternary ammonium salt functionalized alkaline anion-exchange membranes (AEMs), with the same ion exchange capacity (IEC), were synthesized via in situ cross-linking of styrene, acrylonitrile, 1-methyl-3-(4-vinylbenzyl)imidazolium chloride ([MVBIm][Cl]), and N,N,N-trimethyl-1-(4-vinylphenyl) methanaminium chloride ([TMVPMA][Cl]), respectively. The water uptake, swelling ratio, conductivity, and alkaline stability of resultant cross-linked copolymer membranes were investigated. Both types of copolymer membranes exhibit hydroxide conductivity above 10−2 S cm−1 at room temperature. Alkaline imidazolium-type IL functionalized membranes showed an excellent chemical stability of up to 1000 h without obvious loss of ion conductivity, whereas the membranes based on quaternary ammonium salts degraded in high pH solution because of nucleophillic substitution on quaternary ammonium cations. The results of this study suggest that the AEMs based on alkaline imidazolium-type ILs are expected to promote the widespread use of alkaline fuel cells.

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.
