A monolithic sponge catalyst for hydrogen generation from sodium borohydride solution for portable fuel cells

A monolithic sponge catalyst composed of amorphous cobalt boride nanoparticles homogeneously deposited on the fibres of a commercial polyvinyl formal (PVFM) sponge is developed for the hydrolysis of NaBH4. The hydrolysis of NaBH4 is confined within the pores of the sponge without visible liquid and the catalyst can be easily recycled after the reaction. A light weight, low cost and easy to use onsite H-2 generation system for portable fuel cells is developed using the monolithic sponge catalyst.

Automated summary

The monolithic sponge catalyst effectively enhances the hydrolysis of NaBH4 and allows for easy catalyst recycling. A lightweight and cost-effective on-site H-2 generation system for portable fuel cells is developed using this catalyst.
