Economic assessment of hydrogen and electricity cogeneration through steam reforming-SOFC system in the Brazilian biodiesel industry
(2021-01-10)
The increase of environmental concern has led to an increase in biodiesel production, which also produces high amounts of glycerol. This growing production is causing glycerol prices to plummet while constant efforts are ...
Síntese e caracterização de NiO-CGO para anodo e eletrólitos sólidos e base de Céria para SOFC
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2009-01-04)
The direct use of natural gas makes the Solid Oxide Fuel Cell (SOFC) potentially more competitive with the current energy conversions technologies. The Intermediate Temperature SOFC (IT-SOFC) offer several advantages over ...
La/Ba-based cobaltites as IT-SOFC cathodes: a discussion about the effect of crystal structure and microstructure on the O2-reduction reaction
(Pergamon-Elsevier Science Ltd, 2016-10)
This work discusses the effect of the crystal structure and microstructure on the electrocatalytic activity of Lanthanum-Barium cobaltite (LBC), evaluatedas IT-SOFC cathode. Two systems with similar microstructures (particle ...
Characterization of the high temperature properties of BaCe0.4Zr0.4Pr0.2O3−δperovskite as a potential material for PC-SOFCs
(Royal Society of Chemistry, 2021-08)
Compounds based on barium cerates and zirconates, Ba(Ce,Zr)O3−δ, are oxides able to transport protons through their crystal lattice by proton hopping between oxygen sites. This feature makes them potential candidates as ...
Optimum cathode configuration for IT-SOFC using La0.4Ba0.6CoO3−δ and Ce0.9Gd0.1O1.95
(Pergamon-Elsevier Science Ltd, 2012-10)
Three different cathode configurations using porous layers of La0.4Ba0.6CoO3-d (LBC), LBCGDC composite in a 1:1 weight ratio, and GDC were prepared and tested by impedance spectroscopy measurements on symmetrical cells. ...
Active modal damping control of a smart truss structure using a self-organizing fuzzy controller
(Springer, 2015-03-01)
This paper presents design, implementation and experimental results of active vibration control of a truss structure using a pair of piezoelectric ceramic stack actuators. To reduce the vibrations caused by an impulse ...
