Theoretical consideration of electrochemical heat pump systems

摘要: Abstract An electrochemical heat pump consisting of two cells, operating at different temperatures ( T 2 > 1 ), one as a galvanic cell and the other an electrolysis , is proposed. In case that reaction runs in direction negative entropy change reverse occurs system operates pump. A thermodynamic description given, from which expressions for total voltage, reversible exchange, electrical work done on system, output efficiency are derived. The simulated with computer programme using some examples fast reactions. Calculations made concentration conditions such semi-continuous cyclic operation possible by changing directions after each cycle. discussed terms units given off high temperature per unit consumed whole during operation. values obtained galvanostatic cover range 3.90 to 5.47 kJ th /kJ el reactions used calculations.
