NOVELTY - A fuel cell has a container having multi-element stack made of elements. The elements comprise electrolyte layer interposed between cathode layer and anode layer, and are stacked in such a manner that the cathode layer of one element is in direct contact to the anode layer of another element. Each of electrolyte, cathode and anode layers have passage for mixed gas.    USE - For generating power in thermal power plant.    ADVANTAGE - The fuel cell elements are directly joined to each other without using a separator, and hence the fuel cell has a simple structure and provides desired level of voltage. The multi-stack element utilizes components having equivalent coefficient of thermal expansion at the operating temperature of fuel cell by using porous materials. Hence the thermal stress on the components are reduced. The multi-element stack gained a high electric potential by series connection of elements. The mixed gas is passed through the multi-element stack without by-passing, hence running costs of the fuel cell are reduced.    DETAILED DESCRIPTION - A fuel cell comprises a container (20) having a gas inlet (20a), gas outlet (20b) and multi-element stack made of elements (16a,16b). The elements comprise electrolyte layer (10a,10b) interposed between cathode layer (12a,12b) and anode layer (14a,14b). A mixed gas of fuel gas and oxygen containing gas is fed to the fuel cell from the inlet. The elements are stacked in such a manner that the cathode layer of one element is in direct contact to the anode layer of another element. Each of the electrolyte, cathode and anode layers have a passage through which the mixed gas passes.    An INDEPENDENT CLAIM is included for the multi-element stack.
