✦ Synopsis

Abatraet-A generator-detector mode with the rotating nng-dlsk electrode has been used to determme the &fference between Pd and Pt electrode behavior and the ongm of the larger overpotentials at Pd-hydrogen evolving cathodes The use of thm film Pd disk electrodes has allowed full hydrogen or deutenum chargmg of the metal phase m short ties The electrode system has made feasible emultaneous measurements of the hydrogen uptake m PdH, lilms where the -mum composition reached was PdH, 8, Alloymg NI mto Pd decreases the maxlmum hydrogen absorption by sohd solution Pd-Nl films to near zero at 17% NI The outgassmg of hydrogen on open cxcmt from vanously charged electrodes can be followed m real time and shows the losses associated with transfer of specimens to post-analysis
