[Investigation of intermetalloid hydrogen sorption-desorption in physical-chemical life support system].
A hydrogen accumulating alloy was tested for safe sorption and storage of electrolyzed hydrogen within life support system. The alloy of choice was intermetalloid LaNi5 absorbing and desorbing hydrogen at approximately room temperature and pressure A of 20 atm. Sorption was evaluated at hydrogen pressure A of 0.1; 0.2 and 0.3 atm. The rate of desorption was controlled at 2.0 l/min to maintain the standard carbon dioxide and hydrogen feed into the processor. Results of the investigation lead to the main conclusion that the hydrogen accumulating alloy can be an integral component of a new generation of life support systems.
