Electrochemical stability of anodic titanium oxide films grown at potentials higher than 3 V in a simulated physiological solution
(Elsevier B.V., 2007-03-01)
The cathodic behaviour of oxides formed on titanium electrodes in physiological solutions at potentials between 3 and 5 V (vs. SCE) was studied by cyclic voltammetry. In case of anodic polarization at potentials higher ...

An insight into the electrochemical performance of La0.5-XPrxBa0.5CoO3- δ as cathodes for solid oxide fuel cells: Study of the O2-reduction reaction
(Royal Society of Chemistry, 2018-08)
New LT-SOFC cathodes with La0.5-xPrxBa0.5CoO3-δ (0 ≤ x ≤ 0.5) compositions were studied. The La-rich compounds exhibit an inter-growing cubic and tetragonal structure whereas the Pr-rich show a tetragonal structure. Cathode ...
Carbon-supported Pt-Co catalysts prepared by a modifled polyol process as cathodes for PEM fuel cells
(Amer Chemical Soc, 2007-02-22)
In this work, carbon-supported Pt70Co30 nanoparticles were prepared by a polyol process using a long-chain diol as reducer (hexadecanediol) and oleic acid and oleylamine as stabilizers. Depending on the synthesis conditions, ...

Infiltrated La0.5Ba0.5CoO3-δ in La0.8Sr0.2Ga0.8Mg0.2O2.8 scaffolds as cathode material for IT-SOFC
(Elsevier, 2018-10)
The electrochemical response of infiltrated La0.5Ba0.5CoO3-δ (LBC) in porous La0.8Sr0.2Ga0.8Mg0.2O2.8 (LSGM) has been investigated. The thermal expansion coefficient (TEC) of the resulting electrode was measured, obtaining ...

Study of the n=3 Ruddlesden-Popper phases LnSr3Fe1.5Co1.5O10−δ (Ln = La, Pr, Nd) as oxygen reduction electrodes by impedance spectroscopy
(Elsevier Science, 2018-11)
The polarization resistance (Rp) of the n = 3 Ruddlesden-Popper phases LnSr3Fe1.5Co1.5O10−δ with Ln = La, Nd and Pr has been studied by Electrochemical Impedance Spectroscopy as a function of both temperature and oxygen ...
Multi-q pattern classification of polarization curves
(Elsevier BVAmsterdam, 2014-02)
Several experimental measurements are expressed in the form of one-dimensional profiles, for which there is a scarcity of methodologies able to classify the pertinence of a given result to a specific group. The polarization ...
