Fabrication and characterization of large-size electrolyte/anode bilayer structures for low-temperature solid oxide fuel cell stack based on gadolinia-doped ceria electrolyte

Anode-supported microtubular cells fabricated with gadolinia-doped ceria nanopowders

“…In fact, the powders obtained after two milling cycles could be packed down to densities ≥98% of the theoretical density at sintering temperature as low as 1350 • C and with only 2 h of dwell time as it is shown in Fig. 4 [12][13][14]. The excellent sintering behavior of our powders without the need of any sintering additives proves the effectiveness of the powder conditioning by the attrition milling procedure employed in this work.…”

Fabrication and evaluation of anode and thin Y2O3-stabilized ZrO2 film by co-tape casting and co-firing technique

“…A traditional SOFC is generally composed of three components: the electrolyte (8 mol% Y 2 O 3 -stabilized ZrO 2 , YSZ), the anode (Ni-YSZ composite cermet) and the cathode (lanthanum manganite based cathode, La 0.8 Sr 0.2 MnO 3−ı , LSM). However the SOFC still faces a number of challenges that hinder its commercialization, among which are the system reliability and the fabrication cost as well as the major issues in its practical application as a power generator [3]. Therefore, most researches on SOFC are mainly focused on the developments of commercially available SOFC technology with superior electrochemical performance [4,5].…”

Fabrication and Characterization of YSZ/ScSZ Bilayer Electrolyte via Cold-Isostatic Pressing (CIP) Method for Intermediate Temperature-Solid Oxide Fuel Cell (IT-SOFC) Application

“…Therefore, a YSZ/ScSZ bilayer can provide both phase and chemical stability while have superior ionic conductivity compared to other bilayer combinations to operate in low temperatures [11], [14]- [16], [26], [27]. This shows many researchers are suggesting that bi-layered electrolyte material is a solution for intermediate temperature SOFC operation.…”
