Problems solved by technology

NaBH, which is more researched at present 4 System is an example, just there are following problems in the actual use process: 1) raw material cost is expensive; 2) palladium, ruthenium and other precious metal catalysts cost are high, and the service life of the catalyst is short after immobilization (because the hydrolysis reaction is the violent discharge that occurs on the surface of the catalyst. thermal reaction); 3) reaction product sodium metaborate (NaBO 2 ) is easy to block the pipeline; 4) the regeneration and recycling of the reaction by-products is difficult; 5) the stability of the hydrogen storage fuel solution is poor, because NaBH 4 In a metastable state in a strong alkaline aqueous solution, it is easy to spontaneously generate hydrolysis and release hydrogen, which has a very large safety hazard and is not conducive to long-term storage
These defects limit the wide application of this method
