(NL1003862-C2)      The primary carbon dioxide is introduced to the matrix at a distance from the cathode, where the fuel cell comprises a porous cathode, a porous anode and a carbonate-containing matrix wherein the carbonate is fluid, and where the anode is supplied with hydrogenous gas and the cathode is supplied with oxygenous gas and primary carbon dioxide which react to form water, which is led away with carbon dioxide, and carbonate ions which move to the anode to generate a potential. Also claimed is a fuel cell as above where the matrix has: on the anode side an inlet for hydrogenous gas and an outlet for reaction products and unused gas, on the cathode side an inlet for oxygenous gas and an outlet for unused gas, and a channel to distribute the primary carbon dioxide over the matrix. Also claimed is a stack of at least two of the above cells, where: the respective inlets of the cells for hydrogen and oxygen are aligned to form supply conduits for hydrogen and oxygen, the outlets are similarly aligned to form discharge conduits, and the carbon dioxide inlets are aligned as a supply conduit and the outlets are aligned as a discharge conduit. Also claimed is a method of generating electricity using the above fuel cell, wherein water and carbonaceous material are heated by heat exchange to form the hydrogenous gas supplied to the anode, and where the resulting hydrogen depleted gas is at least partially oxidised with an oxygenous gas to generate heat to be recycled for heat exchange. Also claimed is an installation for generating electricity where a reform unit is connected to the anode of a fuel cell, and the outlet of the anode is connected to a secondary reformer which has an opening for an oxygenated gas so hydrogen-depleted gas is oxidised to provide heat exchange for the reform unit.    ADVANTAGE -   In a known fuel cell, supply of carbon dioxide distant from the cathode protects the cathode from the effects of attack by molten carbonate to prolong the life of the fuel cell.
