Patent ID: 7637971

Claim:
A hydrogen fuel supply system comprising: a water tank for storage of water; a methanol tank for storage of methanol; a programmable logic controller for controlling the mixture ratio of methanol and water; a methanol aqueous solution particulates generator including an oscillator and wherein said oscillator is a chip consisting of piezoelectric trasducers for oscillating a mixture of water and methanol to form methanol micro-particulates wherein said methanol aqueous solution particulates generator is a micro-injector for outputting high frequency electric energy by said oscillator to convert the methanol aqueous solution into micro and nano sized mists with particulates of less than 3 μm; a spark plasma heater for heating said generated micro-particulates; a catalyst reactor for reacting said heated methanol micro-particulates to form a gaseous mixture of hydrogen, carbon dioxide and nitrogen; a hydrogen separation unit for separating hydrogen out of said gaseous mixture; a hydrogen cooler for decreasing the temperature of said separated hydrogen to reduce the activation of hydrogen; a hydrogen compressor for increasing the pressure of said separated hydrogen to increase the higher mass-flow rate; and an injection system for injecting said separated hydrogen into hydrogen engines as fuels and wherein the installation angle for said chip having functions of oscillators and piezoelectric transducers is adjustable between 6° to about 45° with respect to the corresponding position of the spark plasma heater adjacent to said chip; and wherein the volume ratio of said methanol in said methanol aqueous solution is controlled between 57.1% to about 75.5%, to control the optimal condition of H 2 production under proper temperature.
