NOVELTY - The process for the production of hydrogen for micro fuel cells, comprises continuously supplying a catalytic bed (14) with an aqueous solution of sodium borohydride, continuously recovering the obtained hydrogen, supplying a micro fuel cell that provides its transformation into electric energy with the hydrogen, continuously discharging a solution of non reacted sodium borohydride and sodium metaborate by-product using a micropump and a microreactor (1) and then transferring it to a respective collection tank (5), and emptying a reaction chamber (6a) using an another micropump (4).    USE - The process is useful for the production of hydrogen for micro fuel cells (claimed) intended for the production of electric energy for a generic portable electronic device.    ADVANTAGE - The process economically ensures continuous and improved production of hydrogen under environment temperature and pressure conditions in a stable way, avoids the consumption and degradation of a poisoning of the catalyst thus providing high performance of the catalytic reaction in the microreactor, and controls the production of hydrogen using simple regulation of the capacity of the sodium borohydride supply and using an amount of catalyst used in the reaction chamber.    DETAILED DESCRIPTION - The process for the production of hydrogen for micro fuel cells, comprises continuously supplying a catalytic bed (14) with an aqueous solution of sodium borohydride, continuously recovering the obtained hydrogen, supplying a micro fuel cell that provides its transformation into electric energy with the hydrogen, continuously discharging a solution of non reacted sodium borohydride and sodium metaborate by-product using a micropump and a microreactor (1) and then transferring it to a respective collection tank (5), and emptying a reaction chamber (6a) using an another micropump (4). The aqueous solution of sodium borohydride is buffered with a pH of 14 through an aqueous solution of sodium hydroxide (4 wt.%), and stored at environment temperature and pressure in a suitable tank. An INDEPENDENT CLAIM is included for an apparatus for the continuous production of gaseous hydrogen.
