Summary: Proton-conducting solid oxide fuel cells (H-SOFCs) are highly efficient energy devices that operate at intermediate temperatures due to their high ionic conductivities. However, the role of oxygen-ionic current (jO) in proton-conducting electrolytes has been overlooked. This study presents a theoretical analysis, considering various factors, to evaluate jO in H-SOFCs. The modeling results demonstrate that jO is mainly influenced by fuel humidity, and reducing it can improve the power density of H-SOFCs.

Summary: This study compared the performance characteristics of a direct ammonia fuelled protonic-conducting tubular solid oxide fuel cell (NH3-T-SOFC-H) with the corresponding hydrogen-fuelled one and direct ammonia feed oxygen-ion conducting tubular solid oxide fuel cell (NH3-T-SOFC-O) under the same operating parameters and geometrical shape. The results showed that NH3-T-SOFC-H has outstanding performance at intermediate temperatures, while NH3-T-SOFC-O shows promise at higher operating temperatures.

Summary: The development of solid oxide cell (SOC) based on proton-conducting electrolyte is hindered by performance degradation caused by mismatch in thermal expansion coefficients between the electrolyte and the oxygen electrode. This paper proposes a solution by increasing the TEC of the electrolyte and demonstrates the improved stability of SOC with Fe-doped electrolyte and oxygen electrode materials. The Fe doping increases the TEC of BaZr0.3Ce0.5Y0.1Yb0.1O3-delta electrolyte and decreases the TEC of PrNi0.5Co0.5O3-delta oxygen electrode material.

Summary: Proton-conducting Sr0.6Ba0.4Ce0.9M0.1O3-8 (M = In, Pr, Ga) electrolytes without Zr were synthesized using the glycine-nitrate process for intermediate-temperature solid oxide fuel cell (SOFC) applications. The electrolyte powders were analyzed for thermal decomposition and crystalline structure. The morphological structure, chemical stability, and proton conductivity of the electrolyte pellets were examined. It was determined that Sr0.6Ba0.4Ce0.9In0.1O3-8 is the best electrolyte in terms of sinterability, chemical stability, and proton conductivity.

Summary: A bilayer composite electrolyte is designed to improve the stability of co-ionic conducting solid oxide fuel cells (SOFCs) in a cell imbalanced stack. Local electronic conduction is identified as a crucial factor for the durability of co-ionic SOFCs under negative voltage operation. The bilayer configuration is suggested as a practical solution to protect the cells in a cell-imbalanced stack.
