Descrição

The electrochemical behaviour of antimony-lead melt on saturation with oxygen was studied to assess further prospects of such melts as anode materials for high-temperature fuel cells. A perovskite ceramic was used as a robust current collector material. The related mechanisms of alloying and phase segregation were revealed at different melt oxidation levels using combined impedance spectroscopy and thermodynamic analysis.
