“…Increasing importance is being given to the properties of the hydrogen storage alloys [8], the characteristics of the heat and mass transfer within the reaction bed [9] and the optimum structure design [10] to improve the efficiency and performance of the metal hydride heat pump. In the present work, the experimental set-up of metal hydride heat pump was established and four reaction beds with fins improving heat and mass transfer were adopted to ensure successive heat pumping and heating processes.…”
