Abstract

The invention provides a method and a device for preparing hydrogen by hydrolysis of hydroboron, and an application. The method comprises the steps of preparing hydrogen by hydrolysis of hydroboron under an alkaline condition; loading metal cobalt and metal cerium or zirconium to a molecular sieve as a bimetallic catalyst; and adding urea as a reaction stabilizer. By adopting the method and the device, hydrogen production by hydrolysis of hydroboron known at present is selected as an efficient hydrogen production system; a novel stabilizer is added to control the intense degree of the reaction and keep the hydrogen production rate stable; the reaction is more efficient by adopting a homemade catalyst; and simple purification is carried out in a hydrogen collection process. The hydrogen production method can be directly applied to a miniature fuel cell with certain powder; and extra storage, purification and drying devices are not needed.

Description

technical field [0001] The invention belongs to the field of clean energy utilization, and relates to a method for preparing hydrogen, in particular to a method, device and application for preparing hydrogen by hydrolyzing borohydride. Background technique [0002] In recent years, with the development of society and technology and the depletion of fossil fuels, the development of new energy sources such as hydrogen has become a research hotspot. As an important field of hydrogen energy application, proton exchange membrane fuel cells have always attracted much attention. At present, great progress has been made in the research of large and medium-sized fuel cells such as proton exchange membrane fuel cells for vehicles. However, with the need for small fuel cells in special fields, the miniaturization of fuel cells has gradually become an urgent problem to be solved. At present, the method of supplying hydrogen to fuel cells is mostly high-pressure hydrogen storage, but fo...
