Abstract Scope |
Solid oxide fuel cells (SOFCs) efficiently convert the chemical energy in fuels into electricity. However, the elevated working temperature (800-1000 ̊C), and the long-term performance/durability are the main obstacles limiting practical applications. Proton-conducting SOFCs (H-SOFCs) has attracted increased interest in recent years due to the lower working temperatures (400-700 ̊C) and a lower activation energy for proton transport as compared to oxygen ion systems. The structure of these protonic ceramic materials, the characteristics of proton conducting mechanisms, and the materials development for electrodes (anode and cathode) based on mixed ionic-electronic conductors will be summarized. Techniques for device fabrication including a one-step phase inversion method for anode design and additive manufacturing methods for ceramic devices will be discussed. |
