Catalytic surface promotion of highly active La0.85Sr0.15Cr0.8Ni0.2O3−δ anodes for La5.6WO11.4−δ based proton conducting fuel cells

- La0.85Sr0.15Cr0.8Ni0.2O3−δ (LSCN) anodes were promoted through Ni infiltration.
- Ni infiltration allowed strongly diminishing the low-frequency impedance.
- Ni dispersion is very high on LSCN grain, in the form of metallic nanoparticles.
- The low anode resistance of 0.47 Ω cm2 at 700 °C is enough for practical operation of PC-SOFC.
