Abstract Developing high‐performance, cost‐effective protonic ceramic fuel cell (PCFC) cathodes involves navigating complex compositional landscapes to optimize multiple competing properties. This study presents a novel integrated methodology that combines computational screening with machine learning potentials, targeted experimental validation, and Bayesian optimization accelerate the design of Co‐substituted Ba 0.95 La 0.05 FeO 3‐δ (BLF) cathodes. Utilizing optimization, BLFC15 (15% Co)...
Hydrogen peroxide has been an attractive oxidant in direct liquid fuel cells. However, hydrogen reduction reaction heavily relies on noble metal-based electrocatalysts. In this work, a carbon mat decorated with FeCoNi alloy nanoparticles (namely FeCoNi/CM) of ultralow loading, that is, 0.146 mg cm−2, for is designed, fabricated, and applied as free-standing cathode passive alkaline-acid ethylene glycol cell. A piece Pd/C coated cloth (1.0 cm−2) used the anode pre-treated Nafion 211 membrane...
Protonic ceramic fuel cells (PCFCs) offer a promising, clean, and efficient energy conversion solution. However, thermal mismatch between cathodes electrolytes remains critical obstacle, leading to interfacial damage such as cracking delamination. Incorporating negative expansion (NTE) materials into the cathode can mitigate this issue. The challenge lies in integrating NTE without compromising electrochemical performance or causing unwanted reactions during sintering. This study introduces...
