A wind-solar energies-driven hydrogen production system that takes into account the self insulation at electrolytic cell is proposed,which uses a heat storage tank to recover and utilize the spent heat from the working state of the electrolytic hydrogen production.Heat release and insulation are carried out when the electrolytic cell needs to be standby insulation.The new system reduces the power consumption when the electrolytic water hydrogen production equipment stands by,and reduces the heat loss of electrolytic cell.This system can provide some references for electrolytic water hydrogen production in China.
