Galvanic seawater cell
First Claim
1. Galvanic seawater cell for use with seawater as an electrolyte and with oxygen, hydrogenperoxide or chlorine dissolved in the seawater as an oxidant, said cell comprising:
- at least one anode element; and
at least one cathode element, each said cathode element further comprisinga plurality of electrochemically active conductive fibers,a current collecting conductive body extending along a main axis, andmeans for physically and electrically connecting said fibers to said current collecting conductive body such that a substantial portion of each of said fibers extends outwardly from a respective adjacent surface portion of said current collecting body, and said fibers are substantially uniformly distributed about said main axis.

Abstract
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.
