Abstract

The invention discloses a water electrolysis hydrogen production system and an implementation method thereof, and relates to the field of hydrogen production, the water electrolysis hydrogen production system comprises a temperature monitoring unit; a data processing unit used for processing a result output by a data conversion unit and forming a heat dissipation adjustment suggestion matched with the temperature monitored by the temperature monitoring unit; a control unit which is used for forming a control command corresponding to the adjustment suggestion after the data processing unit outputs the adjustment suggestion; a heat dissipation unit which comprises a plurality of heat dissipation modules installed at all positions of an electrolytic bath in a distributed mode; and a heat dissipation unit which is used for executing a control instruction output by the control unit on the data processing unit. The high-temperature position of the electrolytic bath is cooled, the cooling power is matched with the actual temperature, and when the heat dissipation unit is out of action, the hydrogen production system is shut down, so that the heat dissipation unit can be prevented from consuming excessive energy, and the energy utilization is reduced.

Description

technical field [0001] The invention relates to the field of hydrogen production, in particular to a hydrogen production system by electrolyzing water and a realization method thereof. Background technique [0002] At the moment when fossil energy is gradually depleted, finding efficient and sustainable clean energy has become the focus of current research. Among them, hydrogen energy has the advantages of high gravimetric energy density, non-polluting and renewable products, and is an ideal clean energy. Among various methods of hydrogen production, electrolysis of water meets the requirements of energy regeneration and reduction of environmental pollution, and is a clean, efficient and sustainable hydrogen production method. [0003] In the hydrogen production system, the electrolyzer is an important part. The electrolyzer is always in a state of high temperature, and it needs to be dissipated by a cooling device. However, the existing cooling devices usually keep runnin...
