摘      要：A Solid Oxide Fuel Cell(SOFC)is an electrochemical device that converts the chemical energy of a substance into electrical energy through an oxidation-reduction *** electrochemical reaction of a solid oxide fuel cell(SOFC)generates heat,and this heat can be recovered and put to use in a waste heat recovery *** addition to preheating the fuel and oxidant,producing steam for industrial use,and heating and cooling enclosed rooms,this waste heat can be used for many more productive *** large waste heat produced by SOFCs is a worry that must be managed if they are to be adopted as a viable option in the power generation *** light of these findings,a novel approach to SOFC waste heat recovery is *** SOFC is combined with a“Thermoelectric Generator and an Alkali Metal Thermoelectric Converter(TG-AMTC)to transform the excess heat generated by both the SOFC and the *** proposed TG-AMTC is evaluated using a number of performance indicators including power density,operating temperature,heat recovery rate,exergetic efficiency,energy efficiency,and recovery *** experimental results state that TG-AMTC has provided an exergetic efficiency,energetic efficiency,and recovery time of 97%,98%,and 23%,*** study proves that the proposed TG-AMTC for SOFC is an efficient method of recovering waste heat.
