| Research Abstract |
A new type high-temperature heat pump system using thermally regenerative electrochemical cells is proposed in this study. The system covers high temperature range from 600 Kto 900 K. The thermodynamic cycle of the proposed heat pump system is same as the inverse thermodynamic cycle of the alkali metal thermal to electrical converter (AMTEC). The selected working fluid is sodium and the electrolyte material is beta”-alumina solid electrolyte ceramics. The performance of the heat pump based on the experimental electrode performance in this study has been estimated.The typical calculated the coefficient of performance (COP) is 3-4.5 for ΔT = 100 K.
