Abstract
Hydrogenated metal-proton conductor heterostructures are of great applied and fundamental interest in connection with the possibility of forming proton heterojunctions of PdH x | KOH · nH2O type. Here, original compositions, such as Pd|(NaOH + KOH)|Pd, Pd|CsHSO4|Pd, Ti|KOH · H2O|C, and Ti|KOH · H2O|Ti, are synthesized and studied in the temperature range 320–430 K. After electrochemical activation a stable potential difference from 0.8 to 1.4 V (depending on physicochemical conditions) arises between the electrodes of the heterostructures. Part of the potential difference (≈0.8 V for Pd and 0.1–0.2 V for Ti) is due to proton heterojunctions, which are found to be kinetically reversible.
