What claimed is: 1. An electrolytic cell for producing nitrogen gas by electrolysis, comprising: (a) an anode; (b) a cathode; and (c) an electrolyte comprising an active nitrogen compound selected from the group consisting of triazoles, aminotriazoles, tetrazoles, aminotetrazoles and salts thereof,
What claimed is: 1. An electrolytic cell for producing nitrogen gas by electrolysis, comprising: (a) an anode; (b) a cathode; and (c) an electrolyte comprising an active nitrogen compound selected from the group consisting of triazoles, aminotriazoles, tetrazoles, aminotetrazoles and salts thereof, wherein said active nitrogen compound is an anode reactant, said cell further comprising a cathode depolariser to suppress hydrogen formation at the cathode. 2. The electrolytic cell of claim 1, wherein the active nitrogen compound is an aminotetrazole or an aminotetrazole salt. 3. The electrolytic cell of claim 1, wherein the cathode depolariser is nitro-ethanol, nitromethane, isonicotinic acid, a nitrate salt or a chlorate salt. 4. The electrolytic cell of claim 1, further comprising a co-solvent. 5. The electrolytic cell of claim 1, further comprising an antifreeze agent. 6. The electrolytic cell of claim 5, wherein the antifreeze agent is acetone, glycerol, ethylene glycol, or DMSO. 7. The electrolytic cell of claim 1, wherein the anode and the cathode comprise a polymer impregnated graphite, GRAFOIL��, graphite paper, graphite felt or graphite cloth. 8. The electrolytic cell of claim 1, wherein the active nitrogen compound is the aminotetrazole 5-amino-1H-tetrazole. 9. The electrolytic cell of claim 8, wherein the cathode depolariser is an alkali or alkaline earth nitrate salt and a co-solvent is DMSO. 10. The electrolytic cell of claim 9, wherein the anode and the cathode are polymer impregnated graphite. 11. The electrolytic cell of claim 1, wherein the active nitrogen compound is the aminotetrazole salt potassium 5-amino-tetrazole. 12. The electrolytic cell of claim 11, wherein the anode is GRAFOIL�� and the cathode is graphite cloth. 13. The electrolytic cell of claim 12, wherein a cathode depolariser is isonicotinic acid or an alkali or ammonium salt thereof, or an alkali or alkaline earth nitrate salt. 14. The electrolytic cell of claim 13 further comprising an antifreeze agent. 15. The electrolytic cell of claim 1, wherein the anode is GRAFOIL��, the cathode is graphite cloth, and the electrolyte is an aqueous solution comprising 10% by weight of potassium 5-amino-tetrazole, 10% by weight of 5-amino-1H-tetrazole, 8% by weight of isonicotinic acid, 6% by weight of lithium nitrate and 40% by weight of dimethylsulphoxide. 16. The electrolytic cell of claim 1, wherein the anode and cathode are Nylon�� impregnated graphite, and the electrolyte is an aqueous solution comprising 26% by weight of potassium 5-amino-tetrazole, 10% by weight of isonicotinic acid and 40% by weight of dimethylsulphoxide. 17. The electrolytic cell of claim 1, further comprising a transducer for capturing the nitrogen gas generated at the anode and producing mechanical energy therefrom. 18. The electrolytic cell of claim 17, wherein the transducer is mechanically coupled to a fluid dispenser so that a fluid is dispensed from the fluid dispenser when nitrogen gas is generated at the anode.
