Abstract.
The electrochemical quartz crystal microbalance (EQCMB) method has been used to study the processes of hydrogen absorption/desorption in Pd-Ni alloy electrodes. It was found that hydrogen electrosorption is accompanied by an additional frequency shift, attributed to the stresses generated inside the alloy. The influence of stresses on the EQCMB response depends on the amount of absorbed hydrogen and the alloy composition. From the comparison of the EQCMB results with Pd-Ni alloy absorption capabilities data, it was concluded that the decrease of the hydrogen sorption capacity at a Ni content of ca. 25–30 at% is due to an excessive generation of stresses in the alloy lattice. Also, a dependency of the rate of hydrogen absorption in Pd-Ni alloys on potential is reported.
