Investigation of Enhanced CO Tolerance in Proton Exchange Membrane Fuel Cells by Carbon Supported PtMo Alloy Catalyst
Open accessAbstract
We report a two‐ to threefold enhancement of tolerance in a proton exchange membrane (PEM) fuel cell, exhibited by carbon supported nanocrystalline as compared to the current state of the art electrocatalysts. The bulk of these nanocrystals were comprised of alloyed with in the ratio 8.7:1.3 as shown by both X‐ray diffraction and in situ extended X‐ray absorption fine structure measurements. Rotating disk electrode measurements and cyclic voltammetry in a PEM fuel cell indicate the onset of oxidation at potentials as low as . Further, the oxidation of exhibits two distinct peaks, indicating redox behavior involving oxyhydroxides of . This is supported by in situ X‐ray absorption near edge structure measurements at the edge. ©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.
