Title: METHOD AND SYSTEM FOR ELECTROLYSER SINGLE CELL CURRENT EFFICIENCY
Abstract:
There is described a method for determining single cell current efficiency in an electrolyser, the method comprising: measuring voltage of a plurality of single cells in the electrolyser; measuring electrolyser current feeding the single cells; detecting one of a shutdown period and a start-up period; and for each single cell: determining a time t taken for a voltage level to reach a predetermined occurrence in a voltage curve after a polarization current has been triggered; and calculating cell current efficiency as a function of the time t.
