We can use the device in U.S. Patent No. 4,936,961 to make hydrogen on-demand from water. The benefit is that 1) the fuel is plain water (no electrolytes added), 2) it eliminates the need for heavy, expensive hydrogen storage tanks, 3) it uses very little electrical current, 4) Device was featured in Part III of the 1998 BBC documentary “It Runs on Water” with Arthur C. Clarke.
