Electro‐osmotic Drag Coefficient of Water and Methanol in Polymer Electrolytes at Elevated Temperatures
Abstract
The electro‐osmotic drag coefficient of water in two polymer electrolytes was experimentally determined as a function of water activity and current density for temperatures up to 200°C. The results show that the electro‐osmotic drag coefficient varies from 0.2 to 0.6 in Nafion®/ H 3 PO 4 membrane electrolyte, but is essentially zero in phosphoric acid‐doped FBI (polybenzimidazole) membrane electrolyte over the range of water activity considered. The near‐zero electro‐osmotic drag coefficient found in PBI indicates that this electrolyte should lessen the problems associated with water redistribution in proton exchange membrane 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.
