NOVELTY - Producing hydrogen from methanol involves delivering a feed mixture of methanol and water to a reactor chamber (5), where the feed mixture is heated with an outgoing reformed mixture; raising the temperature in the upper part of the reactor chamber for further heating and reforming the mixture; cooling the reformed mixture; delivering the cooled mixture to a high-pressure phase separation vessel (7) for separating hydrogen; delivering the remaining liquid mixture to a low-pressure phase separation vessel (8) for separating carbon dioxide (CO2) and recirculating the excess water.    USE - For producing hydrogen from methanol (claimed) used in fuel cell such as high-temperature proton exchange membrane (HTPEM) fuel cell.    ADVANTAGE - The method produces hydrogen in simple and economical way, and with a minimum consumption of water; is suitable for the localized production of hydrogen for automobiles on the site of a fuelling station, thus obviates the need to distribute huge quantities of hydrogen through high-pressure gas pipelines or cryogenic tank trucks from a central production facility, omitted large tanks for the long-term storage of hydrogen at fuelling stations, and the capacity of a hydrogen storage tank at a fuelling station is small the daily sale of hydrogen; is suppresses formation of carbon monoxide.    DETAILED DESCRIPTION - Producing hydrogen from methanol involves providing a feed mixture of methanol and water; delivering the feed mixture to a reactor chamber (5) equipped with an internal heat exchanger, where the feed mixture is heated by heat exchange with an outgoing reformed mixture from the reactor chamber, and where the outgoing reformed mixture is simultaneously cooled by the feed mixture; raising the temperature in the upper part of the reactor chamber for further heating and reforming the mixture; delivering the reformed mixture to a cooling system (6) for further cooling the reformed mixture below ambient temperature; delivering the cooled mixture to a high-pressure phase separation vessel (7) for separating hydrogen from the cooled mixture; delivering the remaining liquid mixture to a low-pressure phase separation vessel (8) for separating carbon dioxide (CO2) from the remaining liquid mixture and recirculating the excess water from the depressurized mixture to a water tank (9) for supplying water for producing the mixture of methanol and water. An INDEPENDENT CLAIM is included for system for producing hydrogen from methanol comprising a methanol tank connected to a mixture chamber through a pump, a water tank connected to the mixture chamber through a pump, where the mixture chamber is connected to a reactor chamber with heating unit and internal heat exchanging unit, through a high-pressure pump, the reactor chamber is connected to a cooling system for cooling down the reformed mixture below ambient temperature, the cooling system is connected to a high-pressure phase separation vessel for separating the produced hydrogen from the cooled mixture, the high-pressure phase separation vessel is connected to a depressurization chamber for separating the produced CO2 from the remaining mixture, the low-pressure phase separation vessel is connected to the water tank for recirculation of water.
