Electrophoretic deposition of La0.6Sr0.4Co0.8Fe0.2O3−δ cathodes on Ce0.9Gd0.1O1.95 substrates for intermediate temperature solid oxide fuel cell (IT-SOFC)

YBa2Cu3O7−x dispersion in iodine acetone for electrophoretic deposition: Surface charging mechanism in a halogenated organic media

“…A recent study demonstrates that dispersion depends on the I 2 -solvent interaction [37], while results in table 1 verify that the amount of I 2 for each system solvent-particle should be optimised. In fact, the surface charge of the particles becomes positive whatever was their nature [19,[33][34][35][36][37][38][39][40][41][42][43][44], and the effective amount of I 2 added is related to the morphologic properties of the particles [38,58,85].…”

“…SiO 2 [19,33], V 2 O 5 [34], Wollastonite [35], Zirconia stabilised with Yttria (YSZ) [36,37], B [38], TiO 2 [39][40][41], LSCF, CGO [42] and LSGM [43,44]. Moreover, I 2 has been also used as dispersing agent in other organic solvents, such as acetilacetone (AcAc) [45][46][47][48], isopropanol (IPA) [49][50][51] or a mixture of acetone (Ac) or acetilacetone and ethanol (EtOH) [37,42,[52][53][54][55].…”

Formation of La0.8Sr0.2MnO3 films as SOFC cathodes by electrophoretic deposition

“…Similar behavior has been reported previously. 10) The difference in morphology could be related to the particle coagulation process in the deposited electrode film. Particle coagulation in an electric field can be described using a modified DLVO interaction force, 13) where increase in an electric field decreases the minimum force of particle coagulation onto the substrate.…”

“…2),9) Santillán et al 10) successfully formed La 0.6 Sr 0.4 Co 0.8 -Fe 0.2 O 3¹¤ (LSCF) films on Au-or Ag-sputtered Ce 0.9 Gd 0.1 O 1.95 and concluded that the microstructure of the LSCF film can be controlled by EPD parameters such as applied voltage, deposition time. EPD can be a practical process of not only a film formation but also morphology control.…”

La1-xSrxCo1-yFeyO3-d (LSCF) Composite as Durable Cathode Materials for Intermediate-Low Temperature Solid Oxide Fuel Cell: Research Review

“…Walau bagaimanapun, masih terlalu sedikit hasil kajian yang dilaporkan mengenai penggunaan kaedah EPD bagi penghasilan elektrod. Berdasarkan kepada kajian kepustakaan yang telah dibuat, Santillán et al (2009) merupakan penyelidik awal yang melaporkan penghasilan fiem nipis berliang bagi katod LSCF ke atas substrat GDC pada voltan kenaan 20 V. Filem katod lantanum strontium ferit (LSF) pula telah berjaya dihasilkan oleh Asamoto et al (2009) Yaseen et al (2007) dengan penggunaan pelarut akueus telah menghasilkan filem BaTiO 3 setebal 1 µm pada tempoh pengendapan 2 minit dengan voltan kenaan 3 V. Penggunaan larutan akueus bagi proses EPD memerlukan agen penyerakan partikel dan bahan tambah untuk memastikan pengendapan filem katod yang baik diperolehi (Cherng et al 2008;Santillán et al 2009;Zhao et al 2006).…”
