In the present work, different metal foams, were realized and experimentally tested in order to define the most suitable ones for heat storage applications. At first, morphology characterization of the materials through an optical microscope was carried out. Subsequently, heat transfer capacity was evaluated by means of a self-developed apparatus at CNR-ITAE, which makes use of Peltier cells for cycling the foam samples, while the temperatures in different part of the foams is measured.

... of cycles with different amplitudes and length, the effect of pore size and thickness of the sample was evaluated. Dynamic characterization of the coated foams was carried out by means of a gravimetric Large Temperature Jump apparatus at CNR-ITAE.
