Abstract: The resistance of silver-palladium thick film resistors decreases and their surface conduction type changes upon heating in a flow of hydrogen at temperatures within 50–100$^\circ$C or hydrogenation in an aqueous acid electrolyte at room temperature. These effects are due to the reduction of PdO (present in the Ag–Pd film) to Pd by hydrogen entering into the resistor material. In the electrolyte, the resistance of samples starts decreasing at the moment of the current being switched on.
