| Popis: | In this work, electrochemical improvement of the SOFC anode material was achieved through the modification of a NiO-YSZ anode composition with a further infiltration of a mixed conductor such as Ce0.8Gd0.2O2−δ (CGO20). This approach rendered improved power densities, 3 times better, compared to non-optimized systems, i.e. 160 mW cm−2 under pure hydrogen, measured at 700 °C, with an OCV of ∼1.1 V. A simple valuation cost survey of the proposed methodology indicated that the improved polarisations can obtained using about 176 mg of Ce(NO3)3·6H2O and 46 mg of Gd(NO3)3·6H2O per cm2. This is equivalent to a cost of 0.8 ∈ of the starting material per cm2 of active anode area. |
