Fabrication of protonic ceramic fuel cells via infiltration with Ni nanoparticles: A new strategy to suppress NiO diffusion & increase open circuit voltage

Presently, most of the cells using BaZr0.8Y0.2O3-δ (BZY20) electrolyte were prepared by a co-sintering process performed between 1400 and 1600 °C. However, during the co-sintering process, Ni diffuses from the anode substrate into the BZY20 electrolyte layer, resulting in the decrease in both the pr...
