This invention relates to a sea water cell which uses wave action to increase the flow of the water through the cathode. The cell has an anode (1) and a cathode (2) arranged in an open cell structure (3) to allow the electrolyte i.e. the sea water, to flow, trough the structure. The cell structure (3) is provided with water flow deflector means (5) causing water flow through the cell to be deflected from the vertical direction when the cell is, suspended from or attached to a buoyancy device (8 13). The cell (3, 11) may be suspended from a substantially non-elastic wire (12) to allow it to follow the vertical movements of the buoyancy device and the sea waves. The water flow deflector(s) …

Why it's free to use
- Filed September 16, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 16, 2011.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 16, 2013.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
