Effect of cobalt-doped electrolyte on the electrochemical performance of LSCFO/CGO interfaces
(IOP Publishing, 2016-06)
In this work, we have studied La0.4Sr0.6Co0.8Fe0.2O3-δ/Ce0.8Gd0.2O2-δ/La0.4Sr0.6Co0.8Fe0.2O3-δ symmetrical cells containing Ce0.8Gd0.2O2-δ electrolytes synthetized with and without the addition of cobalt as sintering aid. ...
Estudo físico-químico da interface eletrólito polimérico/nanotubos de carbono.
(Universidade Federal de Minas GeraisUFMG, 2009-06-29)
A study of interface between carbon nanotubes (CNT) and polymer electrolytes by electrochemical impedance and cyclic voltammetry was accomplished. These two components were investigated independently before the interface ...
Improved Sr0.6La0.4Co0.8Fe0.2O3-δ/Ce0.8Y0.2O2-δ interface for IT-SOFC applications
(Pergamon-Elsevier Science Ltd, 2016-03)
One of the remaining challenges for the solid oxide fuel cell (SOFC) technology is decreasing its operation temperature to the 500-800 °C range in a cost-effective way without diminishing the cell performance. In this work, ...
Effect of electrolyte on the gelation and aggregation of SnO2 colloidal suspensions
(1992-12-01)
Electrolytes may modify the physical-chemical characteristics of colloidal particle interfaces in suspension, which can favour gel or aggregate formation. The influence of NH4Cl loading on the aggregation and gelation of ...
