Electrochemical cell system with thermal energy storage and relative method.

Abstract

Electrochemical cell system (100) which comprises an electrochemical cells arrangement (10), a control unit (20) configured to operate the electrochemical cells arrangement (10) only electrolytic cells or only as fuel cells, a heat unit (40), external to tire electrochemical cells arrangement (10), which is thermally coupled to the electrochemical cells arrangement (10) and which is configured to alternately store heat from the electrochemical cells arrangement (10) to the heat unit (40) and supply heat from the heat unit (40) to the electrochemical cells arrangement transfer arrangement (30) configured to alternately transfer heat from the transfer heat from the electrochemical cells arrangement (10) to the heat unit (40) and from the heat unit (40) to the electrochemical cells arrangement (10)
