In thermodynamics, enthalpy is defined as the sum of the system’s internal energy and the product of its pressure and volume. It could be a state function standardly used in many measurements in various fields e.g., chemical, biological and physical systems at a constant pressure. The work required to establish the physical dimension of system could be expressed by pressure-volume term. As a state, function, enthalpy depends only on the final configuration of internal energy, pressure and volume, not on the path taken to achieve it. The unit of measurement for enthalpy is joule as the international standards and calorie as the British thermal unit. In chemistry, the standard enthalpy of reaction is the enthalpy change when reactants in their standard states as 1 bar pressure and 298 K temperature change to products in their standard states. (Thermodynamics: H = E + pV , Electrochemistry: H = U + pT)
Na-AMTEC directly convert thermal energy into electrical energy, in specific terms, the static energy conversion subjected to electrochemical reaction mainly dependent to its chemical kinetics and temperature is differed from the dynamic energy conversion where system’s internal energy mainly dependent to its pressure and volume via mechanical motion. Particularly in Na-AMTEC, direct conversion of thermal energy into electrical energy is transpired via ionization of natrium as known as reduction and oxidation (REDOX).
In specific terms, by input of thermal energy the static energy conversion 1) ionization of natrium occurred on anodic electrode, 2) divided electron flow on the circuit to do the electrical work, 3) temperature difference between region of the thermal energy input (source, evaporation regime) and the thermal energy output (sink, condensation regime) generates electrical energy as work. The efficiency of Na-AMTEC could be derived as following and these heat engines distinguish themselves from another types of engines by the fact that their efficiency is fundamentally limited by Carnot’s theorem.
Efficiency is defined as the difference of high ... 전체 초록 보기
