Abstract

Ionomer is a key material of proton exchange membrane fuel cells, not simply as it is responsible for proton conduction but as it affects both the local and bulk oxygen transport process in catalyst layers. In this work, a dual-layer cathode design is used to measure the local and bulk transport resistances in the catalyst layer with various ionomer contents in order to provide quantitative details about the effect of ionomer on oxygen transport process. The results reveal that both local and bulk resistances would enlarge with an increase in ionomer content which can be attributed to the variation of ionomer morphology.

  • If the I/C ratio is too high to block the pores of the CL, the blocked pores will hinder gas and water transport, causing increased local and bulk gas transport resistance or flooding.

    “If the I/C ratio is too high to block the pores of the CL, the blocked pores will hinder the gas and water transport, causing increased local and bulk gas transport resistance or flooding [119].”

    From Effect of Catalyst Ink and Formation Process on the Multiscale Structure of Catalyst Layers in PEM Fuel Cells (2022) · cites this paper as [119]

    The Results and Discussion report that higher I/C fills catalyst-layer pores with ionomer and increases both local and bulk oxygen-transport resistance. The paper also discusses water accumulation at high current densities (p. F245), but does not link high I/C or blocked pores to impaired water transport or flooding. (LLM, conf=0.86)

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.
