Summary: The study found that the composite electrode with an 8:2 mass ratio of BSCFN-BZCYYb exhibits the best performance in fuel cells, with a peak power density of 1.14 W/cm2, an electrode polarization resistance of 0.062 ohm·cm2, and a reasonable durability test lasting 24 hours at -0.5A/cm2 at 750 degrees Celsius. Additionally, a stable operation of the cell in dual modes of electrolysis and fuel cell for approximately 50 hours at +/- 0.5 A/cm2 was achieved, demonstrating good reversibility.

Summary: By modifying the cathode/electrolyte interface with a porous BZCYYb interlayer (PBI) in PCFCs, the cathode performance has been significantly improved, achieving high power density at lower temperatures. The use of this interlayer enhances the cathode/electrolyte interfacial structure and increases the triple-phase boundary, resulting in improved overall performance of the fuel cell.

Summary: The lack of sealing technology for PCFC stacks presents a challenge for the commercialization of protonic ceramic fuel cells, but this study successfully used Ag-CuO braze to join the BZCYYb electrolyte to AISI 441 interconnect. By changing the CuO content, the wettability of the braze on the BZCYYb surface can be tailored, leading to a suitable joint microstructure. Additionally, the Ag-CuO braze system shows long-term stability after aging tests, indicating its applicability for fabricating PCFC stacks.

Summary: Solid oxide fuel cells (SOFCs) are efficient electrochemical energy conversion devices that have the potential to become low cost. However, their high operating temperatures have hindered their widespread commercialization. This review summarizes the recent progress in developing materials to lower the operating temperature of SOFCs and discusses the new opportunities and challenges. The focus is on thin film SOFCs, sub-micrometer SOFCs based on microelectromechanical systems, and devices based on proton-conducting oxide electrolyte.

Summary: Protonic ceramic fuel cells (PCFCs) are considered a potential and more efficient upgrade to conventional solid oxide fuel cells (SOFCs) due to their efficient operation at low and intermediate temperatures and nonfuel dilution at the anode during operation. This review provides a detailed exposition of material development strategies for major components of PCFCs and discusses credible science-backed recommendations for synthesis and fabrication of PCFCs materials. Additionally, the opportunities, challenges, and future directions for P-SOFCs are highlighted as well.

Summary: Proton-conducting perovskite oxide BaCe0.7Zr0.1Y0.2O3-delta (BZCY) is prepared using carbonate coprecipitation method with Tween-80 as the surfactant, resulting in well dispersed particles with an average size of 200 nm. The BZCY powder is used as the electrolyte material in a Ni-based anode-supported protonic ceramic fuel cell (PCFC). The electrolyte can be densified without any sintering aids at 1400 degrees C in open air, and the PCFC exhibits a peak power density of 1050 mW cm-2 at 700 degrees C, with a conducting activation energy of 0.36 eV. The superiority of the BZCY powder prepared using the coprecipitation method is demonstrated by comparing it with a BZCY powder made by conventional solid-state reaction method.

Summary: This study investigates the effect of composite cathodes on the electrochemical performance of protonic ceramic fuel cells (PCFCs). It is found that combining proton-conducting oxide with a mixed ionic and electronic conductor or a triple ionic and electronic conductor can significantly enhance the peak power density, with the reduction in non-charge transfer resistance playing a key role.

Summary: Unlike SOCs, PCCs utilize protons as primary charge carriers and show higher ionic conductivity with lower activation energy. They have advantages such as easy gas separation and no fuel dilution, making them an attractive option for commercialization. However, their performance and stability still need improvement compared to SOCs.

Summary: This study presents the performance and durability of protonic ceramic fuel cells (PCFCs) in an ammonia fuel injection environment. The use of a palladium (Pd) catalyst improves the low ammonia decomposition rate in PCFCs with lower operating temperatures. By treating the anode with Pd catalyst, the performance of PCFCs is significantly enhanced, with a peak power density of 340 mW cm (-2) at 500 degrees C. The Pd catalysts are deposited through an atomic layer deposition post-treatment process, improving current collection and reducing polarization resistance in the low-temperature region.
