Abstract
The present invention is directed to an apparatus and method for controllably adjusting a fluid delivery device. The device includes an electrochemical pump capable of transporting a fluid. A displaceable member is positioned between a pump product chamber and a reservoir, wherein the pump product chamber is capable of retaining water generated from the pump. The displaceable member is controllably displaced upon generation of water from the electrochemical pump and the reservoir contains the fluid that is delivered upon displacement of the displaceable member.
