A known electrochemical actuator has two electrodes in a gastight expandable housing, which electrodes form a cell and on which reversible electrochemical processes take place when a DC voltage is applied; to be precise, depending on the polarity, either a gas is produced which increases the pressure inside the housing, or gas is decomposed, so that the gas pressure is reduced. The pressure changes can be converted into a movement, via the expandable housing. In order to achieve a higher speed for the movement processes, and a larger actuating force, a plurality of cells which in each case have a solid electrode (10), at least one separator (9) and at least one correspondingly designed multi-layer electrode are accommodated in a single actuator. A plurality of cells can be connected electrically in series, and a plurality of series circuits can be connected in parallel to a DC voltage source. For the electrochemical processes to take place, a different DC voltage must be set in each case for the possible types of wiring (in series or parallel). <IMAGE> |
