[ In accordance with our invention, we claim:] [1.] An electrochemical syringe pump comprising:a syringe for delivering a supply of fluid;a plunger disposed within said syringe;a pump housing having an inner and outer surface, said inner surface is attached to said syringe, said pump housing comprises:an electrochemical cell;a power supply selectively connected to said electrochemical cell;a current control apparatus providing a limited current to said electrochemical cell from said power supply;a perforating member defined on said inner surface of said pump housing; and,a sealed charge transfer medium reservoir housed between said syringe and said pump housing wherein upon engagement of said perforating member with said sealed charge transfer medium reservoir, said perforating member perforates said sealed charge transfer medium reservoir and releases a charge transfer medium contained in said reservoir to contact said electrochemical cell to assist in a chemical reaction in said cell wherein said reaction causes an increase in pressure on said plunger to deliver a predetermined amount of said fluid.
