The invention discloses a sodium borohydride solution electrolysis hydrogen production device which comprises a device body. The device body is composed of an electrolysis tank and an upper cover. Theupper cover is located on the upper side of the electrolysis tank. A gas output pipe is arranged on the upper side of the upper cover. A cathode column is arranged on the upper side of the upper cover. An anode column is arranged on one side, away from the cathode column, of the upper end of the upper cover. A gas sucking pump is arranged on the outer side of the electrolysis tank. A guide pipe is arranged on the upper side of the gas sucking pump. One end, away from the gas sucking pump, of the guide pipe penetrates the upper cover and extends into the electrolysis tank. A liquid input pipeis arranged on one side of the upper end of the electrolysis tank. Supporting legs are arranged around the bottom end of the electrolysis tank. A waste liquid outlet is formed in the bottom end of theelectrolysis tank. A shell is arranged on the outer side of the electrolysis tank. A liquid level pipe is arranged on one side of the electrolysis tank. The two ends of the liquid level pipe penetrate the shell and are connected with the electrolysis tank in a penetrating manner. According to the device, before electrolysis, air in the electrolysis tank is sucked through the gas sucking pump, andpurity of produced hydrogen is improved as much as possible.
Description
technical field [0001] The invention relates to the technical field of hydrogen production equipment, in particular to a hydrogen production device by electrolysis of sodium borohydride solution. Background technique [0002] Hydrogen is widely used in industry. As an energy carrier, it has many advantages such as high calorific value and no pollution after conversion by fuel cells. It is an ideal energy source in the future. However, for fuel cell users, the acquisition of hydrogen is currently facing many difficulties, which limits the popularization and application of fuel cells. [0003] Sodium borohydride solution electrolysis is a commonly used hydrogen production method, but there is a large amount of air inside the electrolytic tank before electrolysis, and the air will be discharged through the outlet pipe along with the hydrogen during electrolysis, affecting the quality of hydrogen. Contents of the invention [0004] The purpose of the present invention is to p...
