The P-C-T curves for Ti_(0.17)Zr_(0.08)V_(0.35)- Cr_(0.1)Ni_(0.3) and Ti_(0.17)Zr_(0.08)V_(0.35)Cr_(0.1)Ni_(0.3)Mm_(0.01) alloys have been depicted by electrochemical methods. It is shown that as temperature rises, the hydrogen equilibrium pressure of the alloys goes up, but the hydrogen desorbing performance deteriorates. After addition of Mm, the hydrogen equilibrium pressure of the alloy comes down, and the hydrogen desorbing performance meliorates.
