Abstract

The present invention relates to a hydrogen production system (1). The system (1) comprises an electrolyser (10), equipped with an internal tank (101), adapted to produce hydrogen from the electrolysis of water, and a water distribution pipe (62) adapted to connect the internal tank (101) of the electrolyser (10) to a water source (50).Advantageously, the system also comprises an electrolyte tank (20) adapted to contain a quantity of electrolyte equal to or greater than the quantity of electrolyte contained by the internal tank (101) of the electrolyser (10), and a waste tank (30) adapted to contain a quantity of fluid greater than the quantity of electrolyte contained by the internal tank (101) of the electrolyser (10). Furthermore, the system comprises an electrolyte distribution pipe (63) adapted to connect the internal tank (101) of the electrolyser (10) to the electrolyte tank (20), a drain pipe (64) adapted to connect the internal tank (101) of the electrolyser (10) to the waste tank (30), and a water control valve (71) adapted to regulate the flow of fluid in the water distribution pipe (62), an electrolyte control valve (72) adapted to regulate the flow of fluid in the electrolyte distribution pipe (63), and a control valve (73) adapted to regulate the flow of fluid in the drain pipe (64). Finally, the system comprises a control unit (40) connected to the electrolyser (10) and the valves (71-73) to control its operation. In particular, the electrolyser (10) measures at least one operating voltage of the electrolyser (10) and generates at least one electrolyte exhaustion signal based on the at least one measured operating voltage by the electrolyser (10). In addition, the control unit (40):determines an exhaustion of the electrolyte contained in the internal tank (101) as a function of the electrolyte exhaustion signal,forces the electrolyser (10) into a maintenance state,imposes the emptying of the internal tank (101) of the electrolyser (10), by opening the opening of the drain valve (73) for a first drain time,introduces a quantity of rinse water into the internal tank (101) of the electrolyser (10), by commanding the opening of the water control valve (71) for a rinse time, collects the rinse water in the waste tank (30), by commanding the opening of the drain valve for a second drain time, andfills the internal tank (101) of the electrolyser (10) with new electrolyte, by commanding the opening of the electrolyte control valve (72) for a supply time.
