A Methanol Impermeable Proton Conducting Composite Electrolyte System
Open accessAbstract
The concept of a proton conducting, methanol impermeable composite electrolyte system is demonstrated. A three‐layered laminar electrolyte consisting of a dense, methanol impermeable protonic conductor sandwiched between proton permeable electronically insulating layers permits the selective transport of protons while eliminating methanol crossover to the cathode. We demonstrate the selectivity of the composite electrolyte using palladium foil sandwiched between two Nafion™ polymer membranes. The open‐circuit voltage for an fuel cell utilizing this composite electrolyte is unaffected by introduction of methanol to the fuel stream, whereas conventional polymer electrolyte cells suffer severe degradation of performance due to methanol crossover.

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

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.
