Description

technical field [0001] The invention relates to a hydrogen supply system for dehydrogenation reaction of liquid hydrogen source materials, in particular to a hydrogen supply reaction system for liquid hydrogen source materials based on hydrogen fuel cells. Background technique [0002] Hydrogen energy utilization technologies, such as hydrogen fuel cells and hydrogen internal combustion engines, can provide stable, efficient, and pollution-free power, and have broad application prospects in the fields of electric vehicles and mobile devices. In the past 10 years, developed countries such as the United States, Europe, and Japan, as well as Chinese government departments and enterprises have invested huge sums of money to develop the "hydrogen economy", and have made breakthroughs in large-scale hydrogen production and hydrogen fuel cells. In 2015, the world's major automakers (including SAIC) will mass-produce hydrogen fuel cell vehicles. According to the predictions of the ...

AI Technical Summary

Problems solved by technology

Taking Germany as an example, the liquid organic hydrogen storage technology developed can realize the hydrogen absorption and desorption cycle under relatively mild conditions, but the released hydrogen contains by-product gases that are poisonous to fuel cells, and there are also important problems such as low capacity and inconvenient use. Defects: Japan is currently developing hydrogen storage technology based on traditional organic materials such as toluene, but the dehydrogenation temperature is too high (greater than 300°C), and there is also the problem of poisoning fuel cells by by-products

Therefore, the large-scale application of these two hydrogen storage technologies is restricted.
