Analysis of Water Transport in PEFCs by Magnetic Resonance Imaging Measurement
Open accessAbstract
Management of water is one of the most important issues that limits the operation of polymer electrolyte fuel cells (PEFCs). To better understand water transport in polymer electrolyte membranes (PEMs), a one-dimensional model has been analyzed for water transport in a PEM. To increase the model accuracy, magnetic resonance imaging (MRI) experiments were done to determine the optimum parameters for the model. Using the resulting parameters, we programmed the measured number of maximum water content of the membrane in a fuel cell and water transfer coefficient of the membrane surface. The resulting water distribution of the PEM under various operation conditions was consistent with previous MRI measurements.

MRI measurements by Teranishi et al. showed a cell water content response towards equilibrium occurring on the order of 100 s after cell startup.
“Magnetic resonance imaging (MRI) measurements by Teranishi et al. showed a cell water content response towards equilibrium occurring on the order of 100 s after cell startup, which while much shorter than the above is still a significant duration compared to typical timescales of interest for transient PEMFC phenomena [69,128].”

Both experimental and theoretical studies have implicated the load due to membrane swelling in a lowering of the effective water content of the membrane.
“Both experimental and theoretical studies have implicated the load due to membrane swelling in a lowering of the effective water content of the membrane [128,148,152], with an experimental cap on water uptake of λmax = 6.5 reported in one case [128].”

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.
