NOVELTY - A micro component system for producing a syn-gas enriched with hydrogen from hydrocarbon compositions and water, comprises a mixer for producing a feed stock of vaporized hydrocarbons and water vapor; a steam reformer; a combustor for generating heat energy from fuel cell off gas and vaporized hydrocarbons to heat the steam reformer; and an exit from the steam reformer for the syn-gas.    USE - For producing a syn-gas enriched with hydrogen from hydrocarbon compositions and water. It operates in combination with a fuel cell (claimed).    ADVANTAGE - The inventive micro component system is small in size and is volumetrically scalable with respect to flow rates as determined by power requirements for a specific situation.    DETAILED DESCRIPTION - A micro component system for producing a syn-gas enriched with hydrogen from hydrocarbon compositions and water, comprises a mixer for producing a feed stock of vaporized hydrocarbons and water vapor; a steam reformer into which the feed stock is directed; a combustor for generating heat energy from fuel cell off gas and vaporized hydrocarbons to heat the steam reformer; and an exit from the steam reformer for the syn-gas produced in it, including mechanism for providing in the stage(s) in the system a laminar flow of fluid to effect an energy exchange between fluids.    INDEPENDENT CLAIMS are included for:    (a) a micro component power source in which a gas enriched with hydrogen is produced from hydrocarbon compositions and water, comprising interconnected in a cycle, a fuel cell that consumes hydrogen and exhausts an off gas containing hydrogen; a combustor for burning the fuel cell off gas to provide a source of heat energy; a heat exchanger interconnected with the source of heat energy for transferring heat to a steam reformer; a mechanism for introducing hydrocarbon compositions and water from a source into the cycle; a steam reformer for receiving a mixture of hydrocarbon compositions and water and catalytically reforming the mixture into a gas enriched with hydrogen; and a flow path between the steam reformer and the fuel cell for introducing the gas enriched with hydrogen into the fuel cell; and    (b) a cycle useful in a micro component assembly for powering for a fuel cell, comprising combusting a gas mixture including a hydrogen component to heat vaporizer(s) and a steam reformer; providing a vaporized hydrocarbon and water mixture and introducing the mixture into the steam reformer to produce a feed gas; cooling the feed gas and introducing the feed gas into a hydrogen fuel cell; and combusting the off gas from the fuel cell to heat the vaporizer and steam reformer.
