“…Based on the electrode grain growth model by Ryan et al [77], the role of electrode on the overall power degradation was quantitatively investigated and reasons of the degradation were interpreted. Lodhi et al [69,75,78,79] did a lot of simulations to find the effect of electrodes' grain growth on power degradation of PX-3A cells. In the most recent, Lodhi and Briggs [80] studied electrode performance by looking into the parametric changes of the material properties inherent to it with respect to time.…”

SUMMARYThe alkali metal thermal to electric converter (AMTEC) is one of the most promising technologies for direct conversion of thermal energy to electricity and has been receiving attention in the field of energy conversion and utilization in the past several decades. This paper aims to present a comprehensive review of the state of the art in the research and development of the AMTEC, including its working principles and types, historical development and applications, analytical models, working fluids, electrode materials, as well as the performance and efficiency improvement. The current two major problems encountered by the AMTEC, the time-dependent power degradation and relatively low efficiency compared to its theoretical value, are discussed in depth. In addition, a brief comparison of the AMTEC with other direct thermal to electric converters (DTECs), such as the thermoelectrics converter (TEC), thermionics converter, and thermophotovoltaics converter, is given, and combinations of different DTECs to further improve DTECs' power generation and overall conversion efficiency are demonstrated. Future research and development directions and the issues that need to be further investigated are also suggested. It is believed that this comprehensive review will be beneficial to the design, simulation, analysis, performance assessment, and applications of various types of AMTECs.

“…Lodhi et al [14] further dealt with the problem of power degradation in some detail and proposed some suggested measures to diminish loss of power with time. Lodhi et al also investigated temperature dependent of grain growth model for Na-TEC electrodes [15] and BASE performance in an AMTEC [16]. El Genk et al [17] identified a number of design changes to improve the performance of PX-series cells, such as increasing the BASE tube number and the BASE electrode length, developing corrugated BASE tubes, and using highly thermally conductive refractory metals (Ni or Mo) on the cell hot side.…”
