The invention relates to a porous thermoelectric material (5; 5a, 5b): having at 20 DEG C and at atmospheric pressure, a thermal conductivity lower than 100 mW/(m.K) and an electrical conductivity comprised between 20 S/m and 105 S/m, and comprising a matrix made of a thermally insulating material that has a porosity higher than 70%, and that may be filled at least locally with an electrically conductive material (5b), the content of the electrically conductive material being comprised weightwise between 0% and 90% of the total weight of the thermally insulating material.

    本发明涉及多孔的热电材料(5;5a、5b):‑在20℃下且在大气压下具有小于100mW/(m.K)的热导率和介于20S/m与105S/m之间的电导率,并且‑包括隔热材料的基质,所述隔热材料的基质具有大于70%的孔隙率,并且其能够至少局部地填充有导电材料(5b),按所述隔热材料的总重量的重量计算,所述导电材料的含量介于0%与90%之间。
