WebLithium borohydride (LiBH 4) is a complex hydride with a high hydrogen density. It is a strong reducing agent and an electrode material. It has a high gravimetric (18.4 wt%) and volumetric (121 kg/m 3) hydrogen storage capacities. It can also be used in lithium-ion … DBFCs could be produced more cheaply than a traditional fuel cell because they do not need expensive platinum catalysts. In addition, they have a higher power density. The high operating voltage of a DBFC reduces the number of cells (in a series circuit) needed in a stack to achieve a desired rated voltage and thus reduces the stack costs considerably.
