Preparation of High‐Platinum‐Utilization Gas Diffusion Electrodes for Proton‐Exchange‐Membrane Fuel Cells

Taylor, E. J., Anderson, E. B., Vilambi, N. R. K.·1992·Journal of The Electrochemical Society

Abstract

We evaluated an electrochemical catalyzation technique for producing gas‐diffusion electrodes for proton‐exchange‐membrane fuel cells (PEMFC). The electrochemical technique deposits platinum catalyst particles in regions of the electrode that are in ionic contact with the proton‐exchange membrane and in electronic contact with the carbon support. Since ionic and electronic contact are necessary components of catalyst utilization in gas‐diffusion electrodes, the electrochemical catalyzation technique reduces the amount of platinum required for PEMFC. We present data for oxygen reduction and hydrogen oxidation with gas‐diffusion electrodes containing 0.05 mg Pt/cm 2 .

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.
