Stability of Corrosion-Resistant Magnéli-Phase Ti[sub 4]O[sub 7]-Supported PEMFC Catalysts at High Potentials
Open accessAbstract
Substoichiometric titanium oxide -supported Pt catalysts were prepared and their electrochemical properties, particularly the effects of high-potential conditions on the activity and stability of catalysts, were compared to those of catalyst. Polarization measurements using membrane electrode assemblies revealed that the cathode shows a similar activity for the oxygen reduction reaction as catalyst at . A high-potential holding test ( holding at vs anode) demonstrated that the catalyst is quite stable against high potential up to . A single cell using a cathode was operated at , and voltage stability for with was also demonstrated.

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.
