Polarization curves and electrochemical extraction have been used to analyze the electrocatalytic activity of (Ti,V)_3-zCr_z alloys. The correlation between the composition and the optimal temperature of hydrogen desorption, overpressure of hydrogen evolution and amount of reversing hydrogen has been investigated. The obtained results help understand and optimize the process of electrochemical hydrogen saturation in alloys.

Cathodic polarization curves for Ti_0.54V_1.98Cr_0.48 (1), Ti_1.98V_0.54Cr_0.48 (2) and Ti_0.33V_1.27Cr_1.4 (3) in 1 mol·l^-1 solution KОH.
