The invention can be used in devices transforming chemical power to electric power. The main point of the invention is that a fuel cell comprises molten carbonates at temperatures not lower than the melting temperature placed in a housing chamber, a pair of electrodes - anode and cathode, each of them connected to a working gas supply: anode with a fuel gas and cathode with an oxidizing gas, and a surface adjoining the molten carbonates and containing a catalyst for a chemical reaction to run: oxidation on the anode and reduction on the cathode. Each electrode is made in the form of a shell limiting its internal space and filled in with a working gas, further, at least a part of the electrode shell is immersed into the molten carbonates and made of a metal wire or grid to keep the gas inside the electrode shell and the molten carbonates outside the mentioned shell by means of capillary forces. The metal wire of the electrode shell may be produced winded in the shape of spiral with a gap between adjacent coils not exceeding 200 micrometers, whereas the metal grid of the electrode shell may have a cell dimension of 1-200 micrometers. The lithium treated nickel oxide may be used as a cathode catalyst, nickel and its alloys melts may be used as an anode catalyst. Oxygen or air may be used as an oxidizing gas. Hydrogen or synthes gas or methane or natural gas may be used as a fuel gas. A mixture of lithium carbonate, kalium carbonate and natrium carbonate may be used as molten carbonates. |
