PCT No. PCT/NO92/00021 Sec. 371 Date Dec. 3, 1993 Sec. 102(e) Date Dec. 3, 1993 PCT Filed Feb. 6, 1992 PCT Pub. No. WO92/14272 PCT Pub. Date Aug. 20, 1992.This invention relates to galvanic seawater cells and batteries and in particular to cathodes which are suitable for use in galvanic cells that use an oxidant dissolved in the electrolyte as depolarizer. An example of such cells are seawater cells which use the oxygen dissolved in the seawater as oxidant. The cell has an inert electrode which consists of a number of conducting fibers (1,3,14) connected to a conducting body (2,4,15). The fibers (1,3,14) have different orientations relatively to each other and to the body (2,4,15). In a preferred embodiment the electrode body (2,4) consists of two or more wires which are twisted together to constitute an electrode stem while clamping the fibers (1,3) in a fixed position between the wires, as in a laboratory bottle brush.
