Description
Technical Field

Background
Current automobiles rely on mainly non-renewable fossil energy sources. Along with the increasing number of automobiles, the decreasing reserves of fossil energy causes the environmental pollution and the global warming effect to be intensified, and people are forced to find an ideal energy to replace the fossil energy. The hydrogen energy is the ideal energy with the most development potential in the 21 st century, has the advantages of high energy density, cleanness, reproducibility, convenience in utilization and the like, and is the best choice as a new energy in the future. With the rapid development and the increasing maturity of hydrogen fuel cells under the energy and environmental protection strategy of governments, the fuel cell technology has been widely applied to the field of automobile industry, compared with the traditional internal combustion engine, the fuel cell has higher energy conversion efficiency, and because the reaction product is water, no pollutant and greenhouse gas are generated, and the real zero emission is realized.
Although hydrogen energy has many advantages, how to safely store and transport hydrogen energy is a key problem to be solved. The conventional storage mode needs extreme conditions of high pressure and low temperature, has high requirements on the design and construction of a hydrogen storage tank and a hydrogen station of an automobile, and consumes a large amount of energy. At present, a hydrogen station is built in a plurality of cities such as Shanghai, Buddha, Yunfo, Wuhan and the like in China, the construction scale and popularization of the hydrogen station are seriously hindered by the influence of multiple factors such as construction safety and cost, and the current commercial fuel cell automobiles are provided with high-pressure hydrogen storage tanks, so that the fuel cell automobiles are difficult to popularize because the high-pressure hydrogen storage tanks cannot be separated from the hydrogen station. In view of the existing problems, a novel automobile power mode is urgently needed to be designed to overcome the defects of the existing automobile power supply mode, and the development of vehicle-mounted hydrogen production is an effective way for solving the problems. The application of the vehicle-mounted hydrogen production system can be separated from a hydrogen station to work, and has great significance for popularization and promotion of hydrogen energy vehicles.

Wherein, the methanol hydrogen production has the problems of slow starting time, complex gas separation, carbon dioxide in the product and the like, and does not accord with the current energy development direction; the aluminum water reaction hydrogen production has the advantages of simple separation, high hydrogen storage ratio, high hydrogen production purity, no production of products harmful to the environment and the like, and is very in line with the current trend of energy development.
The hydrogen production by the aluminum water reaction has many modes, most commonly hydrogen is produced by a hydrogen generating device under the conditions of medium pressure and low pressure, but the hydrogen production modes with pressure have the problems of higher temperature, higher pressure, small effective volume in the hydrogen generating device, high equipment requirement and the like. When the pressure of the hydrogen generating device is more than 0.1MPa, the temperature of the hydrogen production equipment is higher than 110 ℃, and the reactor of the hydrogen is required to be made into an elliptical shape, so that the hydrogen production space is greatly reduced, the hydrogen production quantity of the system is reduced, and the vehicle-mounted requirement cannot be met.

However, the vehicle-mounted hydrogen generator has two disadvantages that the aluminum alloy is soaked in water in advance and then is heated to react when the reaction occurs: (1) according to the characteristics of the aluminum alloy, the longer the aluminum alloy is soaked in water, the more difficult the aluminum alloy is to react, even the aluminum alloy is not reacted; (2) the reaction box needs to be heated, the volume ratio of the reaction box body is large, the efficiency of heating water by the heater is low, and therefore the problems of long reaction starting time and high type selection power of the heater occur. Moreover, the quantity of the hydrogen output by the vehicle-mounted hydrogen generating device is not controlled, the hydrogen production rate is low, and stable pressure intensity cannot be provided for the vehicle.
Therefore, there is an urgent need for a system for producing hydrogen by reacting aluminum water under normal pressure.
