“…The introduction of small quantities of multivalence cations such as Co, Bi, or Ni in the gallium sites (i.e., La 0.8 Sr 0.2 Ga 0.8 Mg 0.2−x Ni x O 3 ) has been proven to increase the overall performance of LSGM at lower temperatures (ca. 600 • C), while slightly increasing the electronic conductivity [283][284][285]. By incorporating Co, Bi, and Ni into the gallium sites of LaGaO 3 electrolytes, the oxygen ion conductivity can be significantly improved.…”

“…The existence of two cation sites with different sizes in the perovskite structure has expanded the number of possible dopants (i.e., barium and gadolinium) used in perovskitetype electrolytes [285]. For instance, doping with barium instead of strontium has been shown to reduce the octahedral tilt angle of GaO 6 at low temperatures, decreasing the activation energy.…”

Solid oxide fuel cells (SOFCs) are amongst the most widely used renewable alternative energy systems with near-zero carbon emission, high efficiency, and environment-friendly features. However, the high operating temperature of SOFCs is still considered a major challenge due to several issues regarding the materials’ corrosion, unwanted reactions between layers, etc. Thus, low-temperature SOFCs (LT-SOFCs) have gained significant interest during the past decades. Despite the numerous advantages of LT-SOFCs, material selection for each layer is of great importance as the common materials have not shown a desirable performance so far. In addition to the selection of the materials, fabrication techniques have a great influence on the properties of the SOFCs. As SOFCs with thinner layers showed lower polarisation resistance, especially in the electrolyte layer, different thin-film fabrication methods have been employed, and their effect on the overall performance of SOFCs has been evaluated. In this review, we aim to discuss the past and recent progress on the materials and thin-film fabrication techniques used in LT-SOFCs.

“…However, there are difficulties with the soundness of LSGM's bound compositions. Additionally, it has been demonstrated that it is difficult to assemble pure single-section electrolytes of LSGM, and other phases like La 4 Ga 2 O 9 and SrLaGa 3 O 7 have been found near the grain boundaries 36 . Such phases cast questions on the long-term durability of solid oxide cells using LSGM electrolytes, necessitating greater research into this material.…”

Despite being unquestionable around 170 years ago and promising substantial ecological benefits and huge electrical capacity, fuel cells have just presented a serious potential for being commercially practicable. The solid oxide fuel cell has excellent potential and is currently an active research subject. The solid oxide cell might be apparatus composed entirely of solids that operate at very high temperatures, in contrast to other fuel cells. The challenges in developing a high-temperature solid-state fuel cell are discussed in this paper, as are the inorganic materials now employed and under checkup for such cells, as well as the challenges connected with running solid oxide cells on practical hydrocarbon fuels.
