Abstract: An electrochemical actuator forms a sealed gas space inside of which there are a plurality of cells. Each cell has a solid electrode made from an electrochemically reversibly oxidizable material and a counter electrode. By applying a reversible direct current, an electrochemical reaction is initiated which results in a pressure increase or decrease in the gas space that can be used for generating movement. The manufacture of the actuator is simplified and manufacturing costs are lowered by providing a stackable spacer frame for each cell which is constructed of a material that is a relatively good heat conductor and an electric isolator. The rim of a metallic cell cup is attached to the spacer frame and a matrix soaked with an electrolyte is placed inside the cup. Each cell further has a solid electrode, a separator and a counter electrode which, together with the spacer frame, are assembled into a cell. When the cells are stacked, the counter electrode of each cell is placed against the cell cup of the adjoining cell.
