Abstract

The invention discloses a hydrogen production device by hydrolysis of sodium borohydride, which comprises an upper cover plate and several fuel reaction chambers; the upper cover plate and each fuel reaction chamber are distributed sequentially from top to bottom, and An overflow plate is arranged between the upper cover plate and the uppermost fuel reaction chamber; the upper cover plate, each fuel reaction chamber and each overflow plate are fixedly connected, each fuel reaction chamber is provided with a solid fuel, and the fuel of the device The conversion rate is high, the hydrogen production rate is controllable, and the hydrogen production purity is high.

Description

technical field [0001] The invention belongs to the technical field of hydrogen preparation, and relates to a hydrogen production device by hydrolysis of sodium borohydride. Background technique [0002] With less and less reserves of non-renewable resources such as oil, natural gas, and coal, it is imminent to develop new energy sources in today's world. Hydrogen is one of the most widely existing substances, it has become 75% of the mass of the universe, and it is a secondary energy source. Hydrogen energy may play an important role on the world energy stage in the 21st century, and its preparation, storage, transportation, and application technologies will all become topics of great concern today. With the widespread attention of hydrogen fuel cells, a rapid hydrogen production equipment is designed, which is directly used in hydrogen fuel cells and a new type of generator is developed. [0003] There are many ways to produce hydrogen, because metal hydrides have incomp...

[0004] The development of a sodium borohydride hydrogen production device has always been a hot topic at home and abroad. Now the patent CN201821440352.9 discloses a sodium borohydride hydrolysis hydrogen production device, including a water supply device, a feeding chamber, a vibration chamber, a drying chamber, and a cooling chamber connected in sequence. ; The vibration chamber includes a spring piece, a coil, an armature, an iron core, and a connection block; the outside of the feeding chamber is connected and matched with the support seat; the upper end surface of the connection block is welded to the top ground of the support seat, and the upper end surface of the connection block is lower The end face is connected to the iron core, the spring piece is clamped on the connection block, and is located between the connection block and the outer wall of the vibration chamber, the armature is installed on the lower side of the spring piece, and the side of the iron core is provided with a coil; patent CN 201821264402.2 discloses a Sodium borohydride hydrolysis hydrogen production device, the device fills the catalyst unit in the inner cavity of the second container. The catalyst unit includes a carrier layer and a catalyst layer loaded on it. The carrier layer is curled to form a number of fuel circulation channels. The port enters the inner cavity of the second container, and reacts with the catalyst in the process of flowing through the fuel flow channel, and at the same time, the first housing space for accommodating hydrogen is formed between the first shells, but the existing hydrogen production device The fuel conversion rate is low, and the hydrogen production rate is uncontrollable, and the hydrogen production purity is low
