NOVELTY - The system for converting chemical energy into electrical energy, comprises a fuel cell comprising an anode (105) to receive a fuel and a cathode (110) to receive oxygen, and an electrolyte chamber (115) in the fuel cell, including an electrolyte medium in contact with the anode and the cathode to conduct charge from the anode to the cathode and an electrical circuit operatively coupled to the fuel cell to conduct electric current from the anode to the cathode. The electrolyte medium comprises an inorganic salt mixture. The electrolyte medium comprises a liquid component.    USE - The system is useful for converting chemical energy into electrical energy and in power stations for on-site power generation, automotive industry, transportation and mobile communications.    ADVANTAGE - The system avoids the corrosion of electrodes due to the use of acidic or basic electrolyte media.    DETAILED DESCRIPTION - The system for converting chemical energy into electrical energy, comprises a fuel cell comprising an anode (105) to receive a fuel and a cathode (110) to receive oxygen, and an electrolyte chamber (115) in the fuel cell, including an electrolyte medium in contact with the anode and the cathode to conduct charge from the anode to the cathode and an electrical circuit operatively coupled to the fuel cell to conduct electric current from the anode to the cathode. The electrolyte medium comprises an inorganic salt mixture. The electrolyte medium comprises a liquid component, which is free of ammonium. The salts are formed by a transfer of a proton to a nitrogenic inorganic base. INDEPENDENT CLAIMS are included for:    (1) an electrolyte medium for conducting charge from an anode to a cathode in a fuel cell;    (2) a method of converting chemical energy into electrical energy in a fuel cell; and    (3) a fuel cell.
