Effect of alumina additions on the anode|electrolyte interface in solid oxide fuel cells

Thermal shock behavior of ZrB2–SiC ultra-high temperature ceramics with addition of zirconia

“…Zirconia (ZrO 2 ) has been investigated extensively for its excellent fracture toughness, strength, as well as other intrinsic physical and chemical properties [5]. The attractive applications of ZrO 2 -based composites are in the fields of general ceramics [6], electrolytes [7], as well as the thermal barrier coatings [8]. Particularly, the most dramatic increase in the industrial applicability of zirconia has been brought about by the discovery of the stress-induced phase transformation toughening from tetragonal (t-ZrO 2 ) to monoclinic phase (m-ZrO 2 ) [9].…”

Preparation, microstructure and mechanical properties of ZrB2–ZrO2 ceramics

“…[5][6][7] Zirconia ceramics have been investigated extensively for their excellent fracture toughness, strength, as well as other intrinsic physical and chemical properties including hardness, wear resistance, low coefficient of friction and thermal conductivity, and so on. 8 Concerning ZrO 2 -based ceramics, the most attractive application was in the fields of general ceramics, [8][9][10] electrolytes or fuel cells, 11,12 as well as the films or thermal barrier coatings. 13,14 In particular, the most dramatic increase in the industrial applicability of ZrO 2 has been brought about by the discovery of the stress-induced phase transformation toughening from tetragonal to monoclinic phase.…”

Effect of alumina additions in YSZ on the microstructure and degradation of the LSM–YSZ interface

“…A recent study published [5] examines the effect of adding alumina on the anode-electrolyte interface. To the authors best knowledge no studies investigate the cathode-electrolyte interface with alumina additions in the electrolyte.…”
