Abstract: A fuel cell arrangement comprising a number of fuel cell stacks (17, 17?) consisting of planar fuel cells, the stacks being arranged one after the other, each of which being provided with a gas connection for the inlet and outlet flows of the gas of the anode and the cathode side. The fuel cell stacks (17, 17?) are arranged as a tower on a fastening plane element (2, 2?) acting as a load-bearing structure, the tower being supported by means of an end piece (19, 19?) arranged at the end opposite to the fastening plane element (2, 2?) of the tower and by tie bars (11, 11?) connecting the fastening plane element and the end piece. The fastening plane element (2, 2?) is provided with inlet and exhaust flow channels for both anode and cathode side gas, the channels being connected to the common anode and cathode side gas tubes (6, 6?; 7, 7?) of the tower arranged in connection with the tower for arranging the gas connection of the fuel cell stacks.

Abstract: A circuit board assembly including a shielding housing mounted on a circuit board (1), the shielding housing being intended for radio-frequency shieldings. The shielding housing (3) having a wall inclined at an angle .alpha. to a plane orthogonal to the plane of the circuit board. The housing of the circuit board assembly being suitable for at least a partial embedding into an exterior wall of an electronic apparatus.

Abstract: An antenna rod, comprises an antenna lead passing inside the rod and a layer of polymer material outside the antenna lead. The antenna rod has improved characteristic features because the antenna lead has been immersed into the polymer material layer. The antenna rod is produced by inserting the antenna lead longitudinally in a cavity of a casting mold, which is substantially of the shape of the antenna rod and thereafter encapsulating the antenna lead with a polymer material layer. The antenna lead can be reinforced for casting by joining it with a support structure by winding the lead to form a helical coil around the support structure.
