Technical Field

Background

With the increasing importance of people on environmental protection, clean energy is receiving more and more attention. Among the many emerging clean energy sources, hydrogen energy has gained much attention as an important research topic. At present, three main methods for producing hydrogen are available, namely hydrogen production by fossil fuel, hydrogen production by water electrolysis and hydrogen production by biomass. Wherein, the hydrogen production by fossil fuel occupies the largest proportion in all the current hydrogen production, and reaches 95 percent; hydrogen is obtained by partial oxidation reforming of fossil fuels and steam, which is relatively inexpensive and mature in process, but has a serious pollution problem. The method for producing hydrogen by electrolyzing water is environment-friendly and almost has no harmful byproducts, but has huge consumption of electric energy in the production process. The biomass hydrogen production is a novel hydrogen production technology, is relatively inferior to other two technologies, and has low hydrogen production efficiency.

Therefore, the aluminum water reaction hydrogen production has received more and more attention as a new hydrogen production method. Aluminum is the metal element with the largest storage amount in the earth crust, and has the advantages of wide source, relatively low price and relatively low density. It has received much attention in recent years as a new energy source material. Firstly, the aluminum hydrolysis reaction has very high hydrogen yield which can reach 1245mL/g, and the hydrogen storage value is 11.1 percent, so the aluminum hydrolysis reaction is an ideal hydrogen carrier and hydrogen source. Compared with a hydrogen storage tank, the portable aluminum water reaction hydrogen generator has the characteristics of safety, environmental protection, simple device, lower requirement on the device and the like, so that the application range is wider, and the portable aluminum water reaction hydrogen generator can be widely applied to the fields of automobiles, spaceflight and the like.

Patent CN105366639a discloses a portable automatic control aluminum water reaction hydrogen production device, which adopts low melting point metals such as gallium, indium and tin to perform alloying, and activated aluminum reacts with water to produce hydrogen. The device mainly comprises a reaction chamber, a hydrogen storage tank and a liquid storage tank. The hydrogen storage tank is positioned above the reaction chamber, and the liquid storage tank surrounds the reaction chamber and the hydrogen storage tank; the activated aluminum is placed in the reaction chamber in advance, the speed of water entering the reaction chamber is adjusted through the pneumatic valve, the generated hydrogen enters the hydrogen storage tank, and the internal pressure of the hydrogen storage tank is fed back to the pneumatic valve, so that closed-loop control is realized, and the hydrogen with continuous constant pressure is output outwards.

The device has the following defects: 1) The device is complex in design and manufacture, feedback of the pneumatic valve part is difficult to realize, and vacuumizing is needed before reaction, so that additional devices such as a vacuum pump and the like are needed. 2) The apparatus is difficult to replace the reactants. The reactant activated aluminum is added into the reaction chamber from the bottom of the reaction device, and the reaction chamber is filled with liquid after the reaction, so that the replacement and addition of the reactant are difficult. 3) The device utilizes the reactants of low-melting-point metals such as gallium, indium and tin for alloying, the reactants are more active and difficult to store and carry, and certain potential safety hazards exist in the processes of replacement and transportation.

Patent CN1290220C discloses a method and equipment for electrochemical aluminum-water hydrogen storage and hydrogen production, wherein the device is composed of a two-phase circulating filtration closed system consisting of an aluminum alloy polar plate, an electrolyte and a high-activity hydrogen evolution catalytic polar plate. The three-way valve is controlled by the control switch to control the electrolyte to flow into the lower reaction chamber from the upper liquid storage chamber and switch on a circuit switch outside the electrochemical aluminum-water hydrogen storage and production system, so that hydrogen is produced. The electrolyte is pumped back to the upper liquid storage chamber correspondingly by the other connection mode of the three-way valve, so that the three-way valve is separated from the lower polar plate, and an external circuit is disconnected at the same time, so that the reaction is stopped.

The device has the following disadvantages: 1) The device is complex in design and manufacture, and the manufacturing cost of the high-activity hydrogen evolution catalytic polar plate is high. 2) It is difficult to control the reaction rate, i.e., the rate at which hydrogen is produced, with this device. 3) The device utilizes electrochemical process to produce hydrogen, and this process is great to the consumption of electric energy, and the energy consumption is higher, and has higher requirement to the security of container.
