Abstract:
The temperature rise of AB5-type alloys by hydrogen adsorption was limited by their critical temperatures (Tc). We found the relation between the H2 desorption temperatures of metal hydrides at atmospheric pressure (Ts) and their Tc followed the Guldberg rule (Tc = 3/2 Ts), revealing a simple method to estimate Tc.
