Summary:An electrochemical cell having a fluid consuming electrode and a fluid regulating system for controlling the rate of entry of fluids into the cell. The fluid regulating system may include a valve for controlling the rate of entry of fluids into the cell and an actuator for operating the valve. The actuator comprises an ionic polymer that responds to changes in a potential applied across the actuator to open or close the valve. In one embodiment, the actuator comprises at least one conducting polymer. In one embodiment, the actuator comprises polypyrrole, at least one polypyrrole derivative, or mixtures of two of more thereof.
