Abstract

Synchrotron X-ray radiography was utilized to visualize the liquid water distribution in a fuel cell with an active area of 0.48 cm 2 with an effective spatial resolution of 10 μm. Water content was measured in the gas diffusion layers (GDLs), where microporous layer (MPL) thicknesses ranged between 0 and 150 μm. The distribution of liquid water in a substrate-free polymer electrolyte membrane (PEM) fuel cell with a 50 μm-thick MPL was also determined. It was observed that the presence of an MPL significantly reduced the water content at the interfacial region between the catalyst layer and GDL, and increasing the thickness of the MPL led to a reduction of liquid water accumulation at the interface between the substrate and MPL.

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.
