TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The locomotion subsystem comprises a fuel cell (18) and an electrical motor (14); and internal combustion engine. The hydrogen generator includes a hydrophobic cathode comprising a Teflon coating, layer and binder. The cathode operates as hydrogen- generating and as hydrogen-consuming electrode.The refueling subsystem recharges the hydrogen generator while the other hydrogen generator supplies hydrogen fuel to the locomotion subsystem. The motor vehicle also includes a water recycler for supplying water produced by the locomotion subsystem to the refuelable hydrogen generator; an operator controlled hydrogen-fuel generation controller operating in response to an input from a vehicle operator for determining the quantity of hydrogen generated by the generator at a given time. The electrical power is provided by solar cells (24) or regenerative braking. The anode comprises powder, granules, or coated particles. The electrochemical reactor comprises slowly consumable anode and quickly consumable electrolyte. It includes a containing the anode, cathode, electrolyte, and a porous separator sheet between the anode and cathode. It also includes a pulse width modulator between the anode and cathode for controlling the rate of production of hydrogen by the chemical reactor.Preferred Property: The electrochemical cell is replaceable. The coating is formed as coating on a rod that is introduced into the water-based fuel.    TECHNOLOGY FOCUS - METALLURGY - Preferred Material: The slowly consumed anode includes aluminum or aluminum alloy. The anode comprises cadmium, lead, zinc, iron, or tin in sheet and plate forms or in pressed powder and paste pressed on a conducting flat support.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The alkaline electrolyte comprises an alkaline electrolyte based on potassium hydroxide solution or halide electrolyte based on aluminum chloride solution. The electrochemical reactor may include a salt from halides, trihalides, acetates, sulfates, nitrates, borates, acid salts, chromate, stannate, perchlorate, or basic salts of Group (I) metals, ammonium, or Group (II, III) metals; a base; an acid; at least one of zinc, iron, aluminum, magnesium, tin, calcium, lithium, sodium, metal hydrides based on nickels, titanium, rare earth metals, or their alloys; and catalyst based on a metal and metal oxide belonging to platinum metal group or transition metal group.
