1. Method for preventing or greatly reducing formation of calcareous deposits on an inert electron conducting cathode in a primary cell which use natural seawater as electrolyte and dissolved oxygen in the seawater as oxidant, when the cell is connected to a load, comprising the steps:

  • monitoring the cell voltage,disconnecting or reducing the load if the cell voltage falls to a first level the cathode potential corresponding to said first level being above the Nernst potential for the reduction of water to hydrogen and below the Nernst potential for the reduction of oxygen in seawater, andreconnecting or increasing the load when the cell voltage rises to a second level which is larger than or equal to said first level.
