The method of metal-hydride energy conversion predicted 
earlier as a result of numerical modeling and realized in the regime 
of heat waves that propagate in porous media is confirmed experimentally. 
The metal-hydride thermal converter is made up of two channels filled 
with a porous medium. The thermal converting properties of porous 
media are governed by metal-hydride elements (thermal-converter poles) 
distributed along the length of the channels. The elements of each 
channel contain zirconium-based alloys that are capable of rapidly 
and reversibly interacting with hydrogen with the formation of hydrides. 
The effect of the intensification of a cold wave (in a channel with 
low-temperature poles) is confirmed experimentally. Its amplitude 
attains the maximum low temperature that is permissible for a metal-hydride 
pair and exceeds the adiabatic temperature of the hydrogenation reaction 
in the channel of the thermal converter.
