Enhanced oxygen exchange kinetics and long-term stability of a Ruddlesden–Popper phase Pr4Ni3O10+δ cathode for solid oxide fuel cells

Degradation of cathode materials at high temperatures challenges SOFCs commercial viability. This study compares oxygen exchange kinetics of Pr 4 Ni 3 O 10+ δ and La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3− δ , evaluating their stability and suitability for long-term SOFC use.
