Performance of Proton Exchange Membrane Fuel Cell Electrodes Prepared by Direct Deposition of Ultrathin Platinum on the Membrane Surface
Abstract
Proton exchange membrane fuel cell (PEMFC) electrodes were fabricated using a plasma‐sputtering technique that deposits platinum directly on the surface of the Nafion electrolyte. This thin catalyst layer showed remarkable improvement in utilization efficiency, defined as the utilizable portion of the total deposited catalyst. This efficiency, equivalent to 0.043 mg Pt cm − 2 loading of platinum, is about ten times higher than that of the electrodes produced by conventional methods. Application of carbon/Nafion ink on the bare Nafion surface prior to the initial sputtering, and repetition of the sputtering followed by the application of the ink on the treated surface after each sputtering, greatly enhanced the utilization efficiency of the loaded platinum. © 1999 The Electrochemical Society.

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.
