A hydrogen current generator based on palladium nanofilms obtained by thermal-vacuum sputtering on a glass slide has been proposed and created for the first time. Constructively, the nanofilms are divided into two parts. The first part is the nanofilm open surface for interaction with hydrogen, and the other one is covered with a protective layer preventing direct interaction with hydrogen. It was found that in the 100 % hydrogen atmosphere the open-circuit voltage of 10 μV is generated in the structure, while the short-circuit current reaches ~ 300 nA. It is supposed that the hydrogen current generation is related to formation of palladium hydride (PdHx) on the Pd nanofilm open area and emergence of a potential barrier on the Pd/PdHx interface. Keywords: hydrogen, palladium, palladium hydride, ionization, hydrogen current generator.
