Abstract

The invention discloses a bipolar plate of a water electrolysis hydrogen production system and a preparation method and application thereof. The bipolar plate comprises a porous titanium substrate and a niobium nitride film deposited on the porous titanium substrate, and the niobium nitride film has a cubic crystal structure and a hexagonal crystal structure. The preparation method of the bipolar plate comprises the following steps of: preparing a porous titanium substrate by a tape casting method, and preparing the bipolar plate of a water electrolysis hydrogen production tank body from a niobium nitride film in a magnetron sputtering manner under the conditions that the temperature of the porous titanium substrate is controlled to be 400-500 DEG C and the film forming time is controlled to be 60-120 minutes. The corrosion resistance of the bipolar plate is improved, the service life of the bipolar plate is prolonged, the electric energy loss of the water electrolysis hydrogen production tank body is further reduced, and the working efficiency of a water electrolysis hydrogen production technology is stabilized.
