CONCENTRATED SODIUM BOROHYDRIDE SOLUTION WITH STABILIZER

摘要

The present invention improves the efficiency of hydrogen generation in aqueous solution of sodium borohydride with high concentration, and consequently releases 90% or more of hydrogen corresponding to the theoretical value, so that the unit volume when sodium borohydride is used as a hydrogen storage material, A technical implementation of a system that maximizes hydrogen storage capacity per unit mass is included. To this end, a small amount of a stabilizer such as polyacrylic acid was added to the aqueous solution of sodium borohydride. As a result, it was confirmed that the by-product after the reaction was able to use as much hydrogen as possible while maintaining a liquid state. Therefore, it is expected that the fuel system, which makes up a significant portion of both the volume and the mass of the fuel cell system, can be made smaller and lighter, thereby speeding up the commercialization of the mobile fuel cell system.;Sodium borohydride, high concentration, stabilizer, polyacrylic acid
