Resum
This work investigates the activity of copper modified Ce0.50Zr0.50O2 (Cu-CZ) based anodes prepared through subsequent impregnation steps into a porous YSZ matrix. The ceria zirconia oxide was reduced at increasing temperatures and the effect of structural changes on anode performance investigated at 973 K under humidified H-2. Performance of all cells increased after one redox cycle due to a decrease of both the anode polarization and the ohmic resistance of the cell. The redox behaviour of Cu-...
