Abstract: The volume expansion of palladium by electrochemical hydrogen absorption and desorption is used as an actuating mechanism. Palladium films are obtained by electrodeposition from aqueous solution. Actuation based on potentiostatic and galvanostatic signals is investigated in acid and alkaline solutions. Performance characteristics of the actuator are determined. The reversibility of the actuator is hindered by the embrittlement of the Pd layer. The response time strongly depends on the layer thickness (increases for thicker films) and potential (decrease for more cathodic values). The maximum theoretical energy density of the Pd–H actuator is about 5000 kJ/m3. In this work, it is experimentally determined to be around 100–200 kJ/m3.
