High-performance Fuel Cell with Stretched Catalyst-Coated Membrane: One-step Formation of Cracked Electrode
Open accessAbstract
We have achieved performance enhancement of polymer electrolyte membrane fuel cell (PEMFC) though crack generation on its electrodes. It is the first attempt to enhance the performance of PEMFC by using cracks which are generally considered as defects. The pre-defined, cracked electrode was generated by stretching a catalyst-coated Nafion membrane. With the strain-stress property of the membrane that is unique in the aspect of plastic deformation, membrane electrolyte assembly (MEA) was successfully incorporated into the fuel cell. Cracked electrodes with the variation of strain were investigated and electrochemically evaluated. Remarkably, mechanical stretching of catalyst-coated Nafion membrane led to a decrease in membrane resistance and an improvement in mass transport, which resulted in enhanced device performance.

Cracks and interfacial voids present both advantages and disadvantages.
“Cracks and interfacial voids present both advantages and disadvantages [207].”
From Recent Advances on PEM Fuel Cells: From Key Materials to Membrane Electrode Assembly (2023) · cites this paper as [207]
The Abstract says cracks have commonly been considered defects but can be useful when deliberately generated; the Discussion reports improved water transport from the generated electrode cracks. Our copy does not address advantages or disadvantages of interfacial voids, so that part of the claim is unsupported. Page numbers are unavailable in our copy. (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.
