Claims: What is claimed:

1. An apparatus for producing electricity in case of a fire, comprising a housing, water-activated cell element, and a normally sealed vessel of breakable material containing an amount of activation electrolyte therein and having tubular capillary means of breakable material integrally thereof and disposed close to said cell element, said tubular capillary means having thermo-sensitive element of bendable material therein.

2. An apparatus as claimed in claim 1, wherein said cell element comprises an element of porous water-absorbent material having cathode plate and cathode active substance holding one side of said element of porous water-absorbent material, and having anode plate and anode active substance holding the other side of said element.

3. An apparatus as claimed in claim 2, wherein said anode active substance comprises a mixture of silver chloride and pelletized silver pressed on a plate of copper material, and said cathode active substance comprises a plate of magnesium material.

4. An apparatus as claimed in claim 1, wherein said vessel is made of glass material.

5. An apparatus as claimed in claim 1, wherein said thermo-sensitive element is made of nickel-titanium alloy.

6. An apparatus as claimed in claim 1, wherein said activation electrolyte comprises 15% sodium chloride solution.

7. An apparatus as claimed in claim 1, wherein said activation electrolyte comprises water.

8. An apparatus as claimed in claim 1, wherein said activation electrolyte comprises aqueous solution of potassium hydroxide.

9. An apparatus as claimed in claim 1, wherein said activation electrolyte comprises aqueous solution of sodium hydroxide.

10. An apparatus as claimed in claim 1, wherein said housing has an amount of drying material therein.

11. An apparatus as claimed in claim 1, wherein said housing has excess-gas relief safety means thereon which normally keeps said housing sealed.

12. An apparatus as claimed in claim 1, wherein said vessel has pressure gas producing material therein.

13. An apparatus as claimed in claim 12, wherein said pressure gas producing material comprises halogenated hydrocarbons.

14. An apparatus as claimed in claim 12, wherein said pressure gas producing material comprises ethers.

15. An apparatus as claimed in claim 12, wherein said pressure gas producing material comprises hydrocarbons.
