Abstract: A method for arranging at least one battery module and at least one part of a battery housing having a cooling device, which is arranged on a side of the part of the battery housing and which has a predetermined module placement area. In doing so, a thermally conductive component is placed on the cooling device, at least in the predetermined module placement area, and the at least one battery module is inserted in the module placement area and pressed against the thermally conductive component in a pressing direction (R) extending in the direction of the cooling device. Before the pressing, a counter-holder device is arranged on the cooling device, which supports the cooling device during pressing of the at least one battery module in the predetermined module placement area, opposite the pressing direction (R).

Abstract: A miniature electrochemical cell having a volume of less than 0.5 cc is described. The cell casing has a ceramic substrate, preferably of alumina, that is part of a metal-containing feedthrough formed by co-firing a metallic paste in a via hole extending through a green state ceramic. The sintered feedthrough serves as a header assembly that is then joined to an open-ended container by a gold-braze to thereby provide the cell casing. The metallic container serves as a terminal for one of the electrodes, for example the anode, while the metal fill material resulting from sintering the metallic paste serves as the opposite polarity terminal, for example the positive terminal for the cathode.

Abstract: A fuel cell module includes a plurality of power generation cells. Each of the power generation cells includes an electrolyte electrode assembly for performing power generation by utilizing a fuel gas and an oxygen-containing gas. The plurality of power generation cells are stacked together in a circle, and a tightening load is applied to the plurality of power generation cells in a circumferential direction. Each of the plurality of power generation cells has a V-shape, and a peak of the V-shape is oriented to the center of the fuel cell module.
