In this study, a new metal hydride heat pump system driven by an electrochemical compressor was proposed.The system uses the electrochemical compressor to generate absorption heating and desorption cooling in two identical LaNi5 reactors operating at different pressure levels. A thermodynamic model was developed to predict the system performance in terms of various parameters. Modeling shows EC...
In this study, the substitution of Mg with Zr in La0.7Mg0.3(Ni0.85Co0.15)3.5 was carried out with the purpose of improving the electrochemical performances. The structural and hydrogen storage properties in both gas-solid reaction and the electrochemical system were systematically studied on La0.7(Mg0.3−xZrx)(Ni0.85Co0.15)3.5 (x = 0.05, 0.1, 0.2, 0.3) alloys. Each tested alloy is composed of La...
A theoretical model was selected among three potentially applicable models and then used to analyze the absorption isotherms of hydrogen storage alloys LaNi5 LaNi4.75Pb0.25 at different temperatures (T = 303 K, 313 323 K). The expressions were based on statistical physics formalism simplifying hypotheses. one with highest correlation experimental data. had six adjustable parameters: number atom...
