Electrochemical Investigation of the O-2(g),Ni/YSZ System Using Cyclic Voltammetry

Cyclic voltammetry was used for the electrochemical study of a Ni thin film (similar to 880 nm) deposited on an yttria-stabilized zirconia (YSZ) solid electrolyte pellet at temperatures between 350 and 450 degrees C at 20 kPa O-2 and atmospheric pressure. ...

Investigation of the "permanent" electrochemical promotion of catalysis (P-EPOC) by electrochemical mass spectrometry (EMS) measurements

Christos Comninellis, Cyril Falgairette, Chun Xia

The phenomenon of electrochemical promotion of catalysis (EPOC) is most often fully reversible. Subsequent to long-lasting polarization, however, the new steady-state open-circuit catalytic activity after current interruption may remain significantly highe ...

Investigation of the Pt/YSZ interface at low oxygen partial pressure by solid electrochemical mass spectroscopy under high vacuum conditions

Christos Comninellis, Wolfgang Harbich, György Foti, Cyril Falgairette, Chun Xia

The Pt/YSZ interface was investigated at low oxygen partial pressure under high vacuum (HV) conditions at 400 A degrees C. Two different electrochemical techniques were coupled to mass spectrometric gas analysis using a new solid electrochemical mass spect ...

Stored Electrogenerated Promoters Inducing Sustainable Enhanced Pt Catalyst Activity

Cyril Falgairette

This work concerns the investigation of the electrochemical promotion of Pt/YSZ catalyst giving more emphasis to the sustainable enhanced catalytic activity after current interruption. The permanent electrochemical promotion (P-EPOC) of C2H4 combustion ove ...

Charge storage at the Pt/YSZ interface

Christos Comninellis, György Foti, Cyril Falgairette, Arnaud Jaccoud

The electrochemical behavior of Pt/YSZ electrodes in oxygen containing atmosphere at 450 A degrees C has been investigated by double-step chronoamperometry and programmed linear sweep cyclic voltammetry. The response of the O-2(g),Pt/YSZ system in these ex ...
