摘要： A fuel cell comprising a container having a gas inlet and a gas outlet, and a multi-element stack contained in the container and made up of two or more elements for the fuel cell, the element comprising an electrolyte layer, a cathode layer, and an anode layer, with the electrolyte layer being interposed between the cathode and anode layers, and a mixed gas of a fuel gas and an oxygen-containing gas being fed to the fuel cell from the gas inlet, wherein the multi-element stack is formed of the elements stacked in such a manner that the cathode layer of one element is in direct contact to the anode layer of another element, and each of the electrolyte, cathode, and anode layers has a passage through which the mixed gas passes. A multi-element stack for such a fuel cell is also disclosed.

摘要： There are disclosed an assembling apparatus and an assembling method of a nuclear fuel assembly by which flaws or scratches to be formed on the surfaces of the fuel rods can be reduced. The fuel rods are inserted into the grid cells of the supporting grids under the state where the supporting grids are disposed in proximity to each other. Therefore, it is possible to remarkably reduce the fall-down movement of the tip portion of the fuel rod. Conventionally, the tip portion or lower surface of the fuel rod inevitably comes in contact with the grid cell of the supporting grid, so that the scratches might be formed on the surface of the fuel rod, which deteriorates the quality of the fuel assembly. However, according to the present method and apparatus, it is possible to avoid the interference between them so that the scratches to be formed on the surface of the fuel rods can be reduced remarkably.

摘要： The purpose of the present invention is to provide an apparatus which can insert a plurality of hooks into slits of a strap constructing a grid and to hold springs so that the spaces of grid cells are enlarged simultaneously. The enlargement enables insertion of fuel rods into the cells. The apparatus comprises a frame member adapted to attach to the strap along the longitudinal direction thereof, a pair of clamping members engaged the frame member and extending in the longitudinal direction of the strap. Each clamping member can move along the longitudinal direction of the strap. The clamping member has a plurality of projecting hooks arranged in the longitudinal direction of the strap in a spaced relation to one another. The end of the hooks of one of the clamping means are bent toward a longitudinal direction of the strap, while the hooks of another clamping means are bent toward another longitudinal direction of the strap.
