Abstract

We show a criticality of three water morphological transitions on pore-water transport and proton conductivity in Nafion of a polymer electrolyte membrane fuel cell, addressing its pore-size distribution and the Schröder paradox.The first transition leads to the onset of proton conductivity; the second allows for the onset of the capillary percolation channels and proton conductivity jump at a low water content im,H 2 O = 5.Using this as immobile saturation, the predicted water distribution and cell performance are in reasonable agreement with the available experiments.The third ͑the paradox, postulating further capillary advancing͒ bounds the maximum water content on the cathode side of Nafion, which is also supported by the proposed adsorption isobar ͑thermodynamic equilibrium limit͒.These transitions appear in the available pore-size experiments which show capillary percolation channel sizes.In addition, the optimal Nafion pore-water content is between the second and third transitions.

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.
