What is claimed is: 1. A fuel cell for production of electrical energy, comprising a fuel chamber (1) an anode (2a), a cathode (2b), an electrolyte (3) disposed between said anode and said cathode, an oxidant chamber (4), wherein said chambers (1 ) and (4) enclose said anode, cathode and electrolyte, wherein said electrolyte (3) is a ceramic CSC (ceria salt composite) electrolyte with an operating temperature range of 300째-800째 C. and comprising at least one salt and at least one ceria phase, and wherein the electrolyte is sulphate-based CSC for sulphur containing fuels, intended to operate as a high sulphur tolerant CFC device, acting as a pre-gas treatment station and intended to be combined with MCFC power plants. 2. A fuel cell according to claim 1, wherein the electrolyte comprises salts selected from salts that makes the CSC material function as a specific conductor for particular ions. 3.
