  • Disproportionation resistant metal hydride alloys for use at high temperatures in catalytic converters
    Patent number: 5673556
    Abstract: Metal hydrides for absorbing hydrogen which are capable of undergoing repeated charge/discharge cycles of absorbing and desorbing hydrogen at high temperatures and cycles through a high temperature followed by a low temperature. These alloys are intended for use in devices such as heat pumps, heat exchangers, energy storage devices, thermal actuators, temperature sensors and electrochemical cells. The alloys generally comprise the chemical formulaA.sub.1-x B.sub.xwhereA is selected from the group of elements consisting of Ti, Hf, Y,B is selected from the group of elements consisting of Nb, Ni, Co, and Fe,and x is in a range from 0.05 to approximately 0.80, and specific alloys comprise hafnium-nickel (HfNi), hafnium cobalt (HfCo), hafnium-iron (Hf.sub.2 Fe), yttrium-nickel (YNi) and titanium-niobium Ti.sub.1-x Nb.sub.x, where x is in a range of from 0.05<.times.<0.60.
