METHOD OF OPERATING SOLID-POLYMER WATER ELECTROLYSER Russian patent published in 2015 - IPC C25B15/02 C25B1/10 

FIELD: chemistry.

SUBSTANCE: invention relates to a method of operating a solid-polymer water electrolyser, which includes applying dc supply voltage and feeding reaction water into the electrolyser, heating the solid-polymer electrolyser and the reaction water to operating temperature which corresponds to a given electrolysis current while monitoring the present electrolysis current and temperature values, measuring the operating temperature of the solid-polymer water electrolyser which provides the given electrolysis current value, and breaking down water at said temperature and electrolysis current into hydrogen and oxygen. The method is characterised by that measurement of the operating temperature of the solid-polymer water electrolyser is carried out once the electrolysis current during heating reaches its maximum value and begins to fall, having reached the given value.

EFFECT: use of the present invention provides high-speed thermal stabilisation of the electrolysis cell.
