Abstract

This chapter describes the aqueous borohydride solution as a hydrogen storage system. Its applications for supplying gaseous hydrogen to the polymer electrolyte membrane fuel cell are introduced. The contribution describes the borohydride system as a liquid hydride and consists of the following four main topics: (i) borohydride systems as a gaseous hydrogen source; (ii) production of borohydride from borax or a mixture of borate and sodium hydroxide; (iii) hydrogen generation system; and (iv) protide (H) in BH4 complex ions as the source of two electrons per protide and its application to a new type of fuel cell named the borohydride fuel cell.
