This review article focuses on recent advancements in the fabrication techniques for proton-conducting solid oxide fuel cells (PCFCs). PCFCs, which operate at lower temperatures compared to traditional solid oxide fuel cells (SOFCs), offer several advantages such as reduced material deterioration, lower operating costs, and higher efficiency. The construction of PCFCs is crucial for their performance, and various manufacturing methods, including conventional techniques and advanced technologies like 3D printing, are discussed. Conventional methods include solid-state reactive sintering (SSRS), spark plasma sintering (SPS), microwave sintering, tape casting, and hot-press sintering. Advanced methods like 3D printing, particularly laser-based and non-laser-based techniques, are highlighted for their ability to produce complex structures with high precision and efficiency. The article also reviews the microstructure, crystal structure, and electrochemical properties of PCFCs fabricated using these methods, emphasizing the importance of each step in achieving optimal performance. Finally, the future directions for PCFC development are outlined, focusing on reducing energy consumption, improving processing capabilities, and enhancing integration and stability.This review article focuses on recent advancements in the fabrication techniques for proton-conducting solid oxide fuel cells (PCFCs).
