Abstract
A thermochemical system combined metal/metal hydride hydrogen producing process with the AMTEC is discussed in this paper. The thermochemical system consists of dehydrogenation section, AMTEC device, and electrolysis cell. At the high temperature side, the dehydrogenation section and the AMTEC device share direct connected alkali metal working fluid. Thermal input from a heat source is used for dehydrogenation of metal hydride, and then heat and alkali metal are transferred into the AMTEC device, which provides electrical output for the electrolysis cell in the low temperature side. The operational parameters of the direct connected hydrogen producing process are analyzed. The relationship between generative electrical potential of the AMTEC device, temperature conditions and pressure drops is discussed in detail.
