Abstract
The article presents the results of measurements of thermal conductivity coefficients of Pb-Na with the content of the latter of 20 at. % and eutectic (Pb-Bi)-Na 20 at % alloys at temperatures of 350 - 800 °С. The experimental methodology is described and the temperature differences in the heat-conducting sublayer of fuel cells of the studied alloys are estimated.
