Abstract

A perfluorosulfonic acid (PFSA) ionomer, used as the proton conductor in the catalyst layer, influences significantly the performance of proton exchange membrane fuel cell catalyst-coated membrane (CCM). In this paper, SSC-CCM is prepared by the SSC-PFSA (Aquivion, EW 720) ionomer, and the comparative sample (LSC-CCM) is based on the LSC-PFSA ionomer (Nafion, EW 1100). Compared with LSC-CCM, SSC-CCM shows higher porosity, larger electrochemical surface area (ECSA), and smaller high-frequency resistance. Polarization curves of SSC-CCM tested by the short stack show better performance than those of LSC-CCM, especially under the lower relative humidity operations. Moreover, the SSC-CCM outputs higher voltage and is more stable in the dynamic process with temperature continuously increasing under lower relative humidity operation. Such excellent performance of SSC-CCM is confirmed from the higher proton conductivity of SSC-PFSA under low relative humidity. These results indicate that the SSC-PFSA ionomer could be employed for the CCM catalyst layer under the operation conditions of low relative humidity and dynamic running for automotive applications.

  • Aquivion SSC membranes show higher ionic conductivity, higher water absorption, similar mechanical properties, and higher glass transition than Nafion LSC membranes.

    “Compared with the Nafion LSC membrane, Aquivion SSC membranes show higher ionic conductivity, higher water absorption, similar mechanical properties, and higher glass transition [78]”

    From Recent Advances on PEM Fuel Cells: From Key Materials to Membrane Electrode Assembly (2023) · cites this paper as [78]

    The Results and Discussion section (“Water Uptake and Proton Conductivity”; page unavailable) reports higher water uptake and proton conductivity for Aquivion SSC-720 than for Nafion LSC-1100 under the tested conditions, although their conductivities were similar at 20% relative humidity. The Introduction (page unavailable) reports a higher glass-transition temperature for Aquivion at a given equivalent weight. The paper does not report that the membranes have similar mechanical properties. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • Aquivion SSC membranes present better performance in MEA, particularly at low humidity, compared with Nafion LSC membranes.

    “to therefore present better performance in MEA, particularly at low humidity (Fig. 5c).”

    From Recent Advances on PEM Fuel Cells: From Key Materials to Membrane Electrode Assembly (2023) · cites this paper as [78]

    The Results and Discussion section (Static Performance Response to Operation Conditions; page not provided) reports better performance for Aquivion-based SSC-CCMs than Nafion-based LSC-CCMs, with the difference greatest at low humidity. But the Experimental Section (Preparation of CCM; page not provided) says both were made by spraying different electrode-binder ionomers onto the same Gore membrane. The study therefore does not establish that an Aquivion membrane outperforms a Nafion membrane in an MEA. (LLM, conf=0.90)

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.
