A METHOD OF FORMING AN IMPROVED, THERMALLY CONDUCTING ELECTRICALLY INSULATING BOND BETWEEN COMPONENTS OF A THERMOELECTRIC ENERATOR, WHICH METHOD COMPRISES COATING METALLIC CONTACT DISPOSED ON OPPOSITE SIDES OF ELECTRICALLY INTERCONNECTED THERMOELECTRIC ELEMENTS WITH ELECTRICALLY INSULATING AND THERMALLY CONDUCTING FILMS OF CERAMIC MATERIAL, PLATING SAID CERAMIC FILM WITH METAL, JOINING THE METAL PLATING AT ONE SIDE OF THE THERMOELECTRIC ELEMENTS TO A METALLIC COMPONENT OF A FIRST HEAT EXCHANGER BY APPLYING MOLTEN METALLIC BONDING MATEIAL HAVING A MELTING POINT BELOW THE OPERATING TEMPERATURE OF THE FIRST HEAT EXCHANGER, JOINING THE METAL PLATING AT THE OTHER SIDE TO A METALLIC COMPONENT OF A SECOND HEAT EXCHANGER BY APPLYING MOLTEN METALLIC BONDING MATEIAL HAVING A MELTING POINT BETWEEN THE OPERATING TEMPERATURE OF THE SECOND HEAT EXCHANGER, AND SLOIDIFYING SAID BONDING MATERIALS IN SITU, WHEREBY SAID HEAT EXCHANGERS ARE EFFECTIVELY ELECTRICALLY INSULATED FROM SAID THERMOELECTRIC ELEMENTS ALTHOUGH IN THERMALLY CONDUCTING CONNECTION THEREWITH, AND WHEREBY MECHANICAL STRESS IMPARTED TO SAID THERMOELECTRIC ELEMENTS IS MINIMIZED.
