Fremgangsmåde til at hindre kalkdannelser på katoder af havvandsbatterier

摘要

The invention relates to a method for preventing or greatly reducing formation of calcareous deposits on an inert electron conducting cathode in a primary cell (1) which is based on reaction between oxygen, water and a metal anode when it is submerged in seawater and connected to a load (2). The problem of deterioration of the cell (1) caused by calcareous depositions on the cell cathode is solved by monitoring the cell voltage and/or criteria leading to changes in the cell voltage and reducing or disconnecting the load (2) if the cell voltage falls below a certain level (VL) and reconnecting the load (2) after a certain time or when the voltage rises above a certain second level (VH).
