ABSTRACT:
A self-contained device which continuously dispenses a packaged fluid is disclosed. The device is particularly suited for applications where several months may lapse before performance is manually initiated, after which a consistent steady flow is required for an extended period until the packaged fluid is exhausted. The device is particularly suited for applications where ease of fabrication is important. The device utilizes an electrochemicalIy-generated gas, such as oxygen or nitrogen, to pressurize the packaged fluid to dispense it. Oxygen can be electrochemically released from a solid anode material of the general form AxOy as A ions migrate across a suitable ion-conducting electrolyte. Alternatively, nitrogen can be the pressurizing gas wherein it is electrochemically released from a solid, anode material of the general form A'.sub..alpha. N.sub..beta. where A' is a cation, as A' ions migrate across a suitable ion-conducting electrolyte. At the cathode, several possibilities may occur, either the migrated cations are reduced to their elemental state, or a solid material, R.sub.2, where R is a halogen, is reduced to R.sup.-, or solid material, R', where R' is a group VIB element other than oxygen is reduced to R'.sup.-2, or solid material CR.sub.x, is reduced to C+XR.sup.-. The released gas, oxygen or nitrogen, pressurizes a chamber resulting in fluid contained in a flexible bladder within the chamber to be forced through an outlet. Depending on the selection of anode and cathode materials, the device will be self driven or else will require a battery to provide a driving force.
