In combination, a fluid dispenser and an electrochemical cell to produce electric energy by chemical conversion of the fluid to be dispensed. The electrical energy produced is preferably used to operate a device associated with the dispensing of the fluid as, for example, in operation of an electric pump-to-pump fluid from the reservoir. The fluid preferably is dispensed for use after dispensing in some other purpose than as a source for electrochemical energy to dispense fluid from the reservoir. For example, preferred fluid containing alcohol compounds are for use in cleaning and disinfecting.

I claim: 1. A hand cleaning fluid dispenser comprising in combination, a fluid dispenser and an electrochemical cell, the fluid dispenser comprising a dispenser dispensing a hand cleaning fluid onto a person's hand, the dispenser including a reservoir containing the hand cleaning fluid to be dispensed and a dispensing mechanism requiring an electric current to dispense fluid from the reservoir onto a person's hand, the electrochemical cell comprising an electrolyte and two electrodes namely, an anode and a cathode, separated from each other with the electrolyte between the two electrodes, fuel for the cell comprising the hand cleaning fluid from the reservoir in communication with a first of the electrodes, the two electrodes electrically coupled across the dispensing mechanism to provide current flow through the dispensing mechanism by chemical conversion of the fluid at the first of the electrodes. 2. A dispenser as claimed in claim 1 wherein the electrochemical cell is a fuel cell. 3. A dispenser as claimed in claim 2 wherein: atmospheric air containing oxygen is in communication with a second of the electrodes, with chemical conversation of the fluid at the first electrode to provide current flow oxygen is consumed at the second electrode where water is produced. 4. A dispenser as claimed in claim 1 wherein the fluid comprises an alcohol compound which comprises the fuel for the cell. 5. A dispenser as claimed in claim 4 wherein the alcohol compound is selected from methyl alcohol, ethyl alcohol, propyl alcohol, isopropy alcohol, butyl alcohol, isobutyl alcohol, sec-butyl alcohol, tert-butyl alcohol, 1-pentanol, 1-hexanol, ethylene glycol, propylene glycol, glycerol and benzyl alcohol. 6. A dispenser as claimed in claim 5 wherein the alcohol compound is presenting at least 20% by volume of the fluid. 7. A dispenser as claimed in claim 1 wherein the dispensing mechanism comprises a pump for dispensing fluid from the reservoir, the pump having an inlet in communication with the reservoir and an outlet out of which fluid from the reservoir drawn into the pump inlet is dispensed. 8. A dispenser as claimed in claim 7 wherein the first electrode is in communication with the fluid upstream from the pump. 9. A dispenser as claimed in claim 7 wherein the first electrode is in communication with the fluid after the fluid has passed through the pump. 10. A dispenser as claimed in claim 1 wherein the first electrode is in communication with the fuel within the reservoir. 11. A dispenser as claimed in claim 7 wherein the reservoir has an outlet and a passageway for a passage of fluid from the outlet of the reservoir to the inlet of the pump, the passageway being in communication with the first electrode such that at least some fuel in the passageway contacts the first electrode. 12. A dispenser as claimed in claim 1 wherein the reservoir is a collapsible reservoir which reservoir collapses as fuel is dispensed. 13. A dispenser for hand cleaning fluid comprising in combination: a fluid dispenser and an electrochemical cell, the fluid dispenser comprising a reservoir containing the hand cleaning fluid to be dispensed and a dispensing mechanism requiring an electric current to dispense fluid from the reservoir onto a person's hand, the electrochemical cell comprising an electrolyte and two electrodes namely, an anode and a cathode, separated from each other with the electrolyte between the two electrodes, fuel for the cell comprising the hand cleaning fluid from the reservoir in communication with a first of the electrodes, the two electrodes electrically coupled across the dispensing mechanism to provide current flow through the dispensing mechanism by chemical conversion of the fluid at the first of the electrodes, wherein the two electrodes and the electrolyte are all disposed within the reservoir. 14. A dispenser as claimed in claim 13 wherein the reservoir has a liquid outlet at a lower portion of the reservoir and with chemical conversion of the fluid a gas as produced at the second electrode, wherein the gas rises through the fluid in the reservoir to an uppermost portion of the reservoir. 15. A dispenser as claimed in claim 14 wherein the reservoir is collapsible and expandable to accommodate increases and decreases m the volume within the reservoir occasioned by dispensing of the fluid and generation of gas at the second electrode. 16. A dispenser as claimed in claim 13 wherein the fluid is the electrolyte. 17. A dispenser as claimed in claim 2 wherein electrolyte is a protonic exchange membrane having a solid polymer in which protons are mobile. 18. A dispenser as claimed in claim 2 wherein the fuel cell is selected from an alkaline electrolyte fuel cell and an acid electrolyte fuel cell. 19. A dispenser as claimed in claim 13 wherein the fluid comprises an alcohol compound which comprises the fuel for the cell, the alcohol compound is selected from methyl alcohol, ethyl alcohol, propyl alcohol, isopropyl alcohol, butyl alcohol, isobutyl alcohol, sec-butyl alcohol, tert-butyl alcohol, 1-pentanol, 1-hexanol, ethylene glycol, propylene glycol, glycerol and benzyl alcohol, the alcohol compound is present in at least 20% by volume of the fluid.
