“…The precise composition, often a blend of elements carefully chosen for their catalytic properties, orchestrates the performance of nanostructured anodes. In the advanced stages of anode development, Yildirim and his colleagues developed and optimized nanostructured anode material prepared using an infiltration method (Figure 9), in which nickel was infiltrated into the porous YSZ backbone as a catalyst [100]. The fuel cell device using this anode exhibited a significantly enhanced power output (~0.4 W/cm 2 at 800 • C), which is more than double the power (0.174 W/cm 2 ) measured from the reference cell under the same test conditions.…”

“…One important aspect of this technique is that it does not require high sintering steps, making it possible to use electrode supports or novel active materials that either cannot stand high-temperature sintering processes or would react with adjacent cell components at such elevated temperatures [106,107]. Different infiltration process variables such as type of material, substrate type, solution properties, or calcination temperature have been shown to play an important role in the final microstructural properties of the prepared anode layer [108,109]. Although the presence of nanosized materials under SOFC operating conditions could question their long-term stability (due to agglomeration), the high impact of the infiltration process conditions on the nature of the final electrode structure has shown to be of great use in preventing such degradations [110].…”

Recent Advances and Challenges in Thin-Film Fabrication Techniques for Low-Temperature Solid Oxide Fuel Cells

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.

“…While this method increases the TPBs, it does not guarantee the desired anode properties. Another approach involves the impregnation of catalyst and cermet powders to construct a nanocomposite anode structure, , ensuring sufficient pathways for electron collection even with low nickel content. This method satisfies the requirement of percolating networks for active TPBs throughout the anode layer.…”

Solid oxide fuel cells (SOFCs) have gained significant attention as highly efficient energy conversion devices. Enhancing the overall performance of SOFCs relies on the development of efficient anode materials. In this study, an impregnation approach is proposed to improve the electrochemical performance of the nanocomposite Ni-GDC anode by modulating oxygen vacancies and Ni dispersion. This method successfully achieves well-dispersed Ni nanoparticles and adequate oxygen vacancies in the NiO-GDC anode, resulting in excellent TPBs and catalytic activity for SOFCs. The NiO-GDC nanocomposite exhibits a significant improvement in electrochemical activity, reaching a peak power density of 0.37 W/cm 2 at 850 °C. Moreover, it demonstrates remarkable durability with a degradation rate of only 0.1%/h at −380 mA/cm 2 . This study provides valuable insights into the modulation of oxygen vacancies and Ni dispersion in nanocomposite Ni-GDC anodes, underscoring their potential as high-performance materials for solid oxide fuel cells. These findings contribute to the advancement of superior anode materials with improved electrochemical performance, holding tremendous potential for the development of more efficient and reliable SOFCs.
