Wettability of gold, nickel and NiO by molten alkali carbonate under oxidant and reducing atmospheres as relevant to molten carbonate fuel cell

Wettability of gold by molten (Li+Na), (Li+K) and (Li+Na+K) carbonate eutectic systems has been measured by sessile-drop method, as relevant to the problem of adhesion at the molten electrolyte/solid interfaces in molten carbonate fuel cell. The determined parameters and the surface tension data for the respective systems, Reported in the literature, have been used for calculation of the adhesion work parameters for the interfaces under study.
