Description
Technical Field
The invention relates to the field of hydrogen energy and fuel cells, in particular to a solid-state hydrogen storage hydrogen production device and a fuel cell system.
Background
Currently, most vehicles operating on the road are still driven by combustion of gasoline or fuel by an internal combustion engine. In most industrialized countries, motor vehicle internal combustion engines contribute more than 25% of the total emissions of carbon dioxide, a greenhouse gas that contributes to global warming and severely impacts the global environment. In addition, gasoline engines in internal combustion engines also emit pollutants such as CO (carbon monoxide), NOx (nitrogen oxides) and HC (hydrocarbons), lead pollution is also generated when lead-containing gasoline is burned, and diesel engines also emit pollutants such as particulates and NOx.
Currently, the control of engine pollutant emissions is primarily achieved by exhaust gas after-treatment, which generally entails a sacrifice in fuel economy. Research has shown that if a portion of hydrogen fuel (hydrogen, liquid hydrogen, etc.) is introduced into the fuel of an internal combustion engine of a motor vehicle for combustion, the problem of carbon dioxide emissions from the internal combustion engine of the motor vehicle can be significantly improved, while increasing the efficiency of the internal combustion engine. Due to the ease of hydrogen fuel availability and similarity to gasoline fuels, hydrogen may be used as at least a portion of the fuel for internal combustion engines while long-term transport solutions (e.g., hydrogen fuel cell technology) are becoming mature, thereby facilitating the construction and development of hydrogen fuel infrastructure.
The hydrogen fuel cell is used as a power device, has zero emission of carbon dioxide, and is an ideal power device for driving an automobile in the long term. One of the difficulties in promoting energy conservation and emission reduction of automobiles by applying hydrogen fuel and/or fuel cell technology is the problem of storage of vehicle-mounted hydrogen caused by extremely low hydrogen density.
The U.S. department of energy (DoE) hydrogen energy program has established the ideal density of on-board hydrogen storage technologies: the ratio of the weight of stored hydrogen to the weight of the hydrogen storage system is not less than 6.5 wt%, and the bulk density is not less than 62kg of H2/m3. There are many potential hydrogen storage technologies such as compressed hydrogen technology, liquefied hydrogen technology, hydrogen adsorption technology, natural gas reforming technology, alcohol and hydrocarbon reforming technology, water and metal catalytic reduction technology, and slurry hydrogen (slug H)2) Techniques, and the like. In addition, studies have demonstrated the use of sodium borohydride as the on-board H2Potential for storage, highly dilute aqueous sodium borohydride solution can be used to avoid catalyst plugging and maintain reaction efficiency. However, since sodium borohydride is unstable in water, H is continuously produced at a low rate2Excess water to dissolve sodium borohydride can significantly store hydrogen density and cause safety hazards. The results of the studies published to date indicate that none of the above hydrogen storage technologies, apart from other potential problems (e.g., hydrogen storage safety, cost, etc.), has reached the ideal density established by the U.S. department of energy (DoE) hydrogen energy program: the ratio of the weight of stored hydrogen to the weight of the hydrogen storage system is not less than 6.5 wt%, and the bulk density is not less than 62kg of H2/m3. Therefore, there is a need for a hydrogen storage technology that is more efficient in storing hydrogen and has less environmental impact.
