“…It is worth noting that the ionic conductivities of all electrolytes in the ceramic fuel cells with NCAL as a symmetric electrode are above 0.1 S·cm –1 at about 500 °C, which are significantly higher than the intrinsic ionic conductivities of those oxide electrolytes. − It is known to all that the intrinsic ionic conductivity of a GDC electrolyte densified by high-temperature sintering is about 0.012 S·cm –1 at 550 °C, while in ceramic fuel cells with NCAL as an electrode, the ionic conductivity of the GDC electrolyte is significantly increased to 0.045 S·cm –1 . He et al found that in the cells with the NCAL anode, the NCAL anode will be reduced to LiOH/Li 2 CO 3 molten salt in H 2 , which diffused into the GDC electrolyte and then formed a GDC/LiOH/Li 2 CO 3 composite electrolyte.…”

Ceramic fuel cells with Gd0.1Ce0.9O1.95 (GDC) as an electrolyte and Ni0.8Co0.15Al0.05LiO2 (NCAL)-coated foam Ni as a symmetric electrode are prepared. The effect of initial reduction temperature of the NCAL anode on the performance of the cells is investigated. When the initial test temperatures of the three cells were 550, 500, and 450 °C, respectively, the maximum power densities of the three cells at 450 °C were 0.221, 0.125, and 0.02 W·cm–2, respectively. At 450 °C, the ionic conductivities of the electrolytes in the cells with three different initial reduction temperatures were 0.288 (550 °C), 0.165 (500 °C), and 0.011 S·cm–1 (450 °C), respectively. During the test, LiOH/Li2CO3 produced by H2 reduction of the NCAL anode diffuses into the GDC electrolyte, and the interface between LiOH/Li2CO3 and GDC becomes the main channel of ion conduction. The scanning electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and X-ray diffraction results indicated that the amount and the diffusion rate of the LiOH/Li2CO3 mixture diffused into the GDC electrolyte increased with the increase of initial reduction temperature. The LiOH/Li2CO3 mixture entering into the electrolyte will directly affect the effective area or the length of the ion conduction channel formed by the LiOH/Li2CO3 mixture and GDC in the electrolyte, thus significantly affecting the electrochemical performance of the cells.

“…Small well distributed porous nano particle ceria can be clearly observed before the treatment, whereas it becomes sticky and something like glue covers on its surface after treatment. The glue has been reported to be lithium hydroxide, 31,32 which reduces the electronic conductivity and gas leakage issue for the NCAL based fuel cell in this initial stage. Therefore, it is conjected that lithium is transferred from the anode to the cathode after hydrogen treatment, contributing to some of improved electrochemical performance.…”

“…One of the ways to solve the described problem is to decrease the operating temperature of SOFCs and develop fuel cells operating at medium- [36][37][38] and low-temperature ranges [39,40]. This has resulted in investigations into new classes of electrolytes [41][42][43][44] and the development of SOFCs enhanced with nanostructured materials [45,46].…”

Solid oxide fuel cells (SOFCs) are efficient electrochemical devices that allow for the direct conversion of fuels (their chemical energy) into electricity. Although conventional SOFCs based on YSZ electrolytes are widely used from laboratory to commercial scales, the development of alternative ion-conducting electrolytes is of great importance for improving SOFC performance at reduced operation temperatures. The review summarizes the basic information on two representative families of oxygen-conducting electrolytes: doped lanthanum aluminates (LaAlO3) and lanthanum gallates (LaGaO3). Their preparation features, chemical stability, thermal behaviour and transport properties are thoroughly analyzed in terms of their connection with the target functional parameters of related SOFCs. The data presented here will serve as a starting point for further studies of La-based perovskites, including in the fields of solid state ionics, electrochemistry and applied energy.
