Abstract
Thermal conductivity and electrical conductivity coefficients of a metallic porous structure have been estimated. The behavior of the Lorentz number has been analyzed in a wide temperature range and some anomalous features of the Wiedemann-Franz law that manifest themselves at high temperatures in the case where the pores are filled with a gas have been predicted.
