An electrochemical actuator drive system and method that provides for full control of an electrochemical pump system having at least three electrochemical actuators, including two valve actuators, and one pump actuator. The driving circuit is based on a standard H-bridge driving circuit wherein part of the circuit is shared among actuators. Because the system only needs to operate either the pump actuator or one of the valve actuators at any given time, part of the H-bridge driving circuit can be shared among the three actuators, thereby permitting the use of four half-bridge driving circuits.
