摘要:	Much attention has been paid to the concept of using hydrogen used as an energy carrier [1]. In order to overcome the operating problems to satisfy the DOE 2015 target, solid sodium borohydride was used and can achieve 7~9 wt. % of hydrogen storage capacity. Many researchers have focused on: How to improve the catalyst, efficient use of water and testing the hydrolysis performance [2]. Before hydrolysis reaction takes place on the catalyst surface, solid sodium borohydride must dissolve and form a concentration boundary layer. The NaBH4 concentration in the concentration boundary layer is difficult to measure, but it’s very important to understand the profile in the concentration boundary layer of the solid sodium borohydride catalyst hydrolysis reaction. In this work, the concentration profiles in the concentration boundary layer (CBL) must be solved in order to accurately measure the reaction concentration on the catalyst surface.
