Abstract
An electrochemical fluid delivery device according to the present invention includes an electrochemical cell and a flexible bladder having a first chamber for reservoiring a fluid and a second chamber into which gas generated by the electrochemical cell is introduced. The gas compresses the first chamber to deliver the fluid from a delivery port of the first chamber. The bladder is formed of three sheets that are stacked, and their edge portions are joined to each other so that first and second sheets form the first chamber as well as the second sheet and a third sheet form the second chamber. A fluid delivery port and a gas introduction port are provided in the first and second chambers, respectively. The fluid delivery port is also used as a fluid pour port. Alternatively, the fluid pour port is independently provided.
