A process for the production of hydrogen for micro fuel cells, comprises the successive steps of: continuously supplying a catalytic bed with an aqueous solution of sodium borohydride, the catalytic bed being made of at least one metal chosen among cobalt, nickel, platinum, ruthenium with obtainment of hydrogen and of a by-product comprising sodium metaborate, continuously recovering the hydrogen thus obtained and supplying, with said hydrogen as it is as obtained, a micro fuel cell which transforms hydrogen into electric energy. An apparatus provides continuous supply of hydrogen to a micro fuel cell. An integrated system structured for continuously producing and supplying hydrogen to a micro fuel cell and for converting the continuously supplied hydrogen into electric energy.

Process and corresponding apparatus for continuously producing gaseous hydrogen to be supplied to micro fuel cells and integrated system for producing electric energy

A device for producing energy for portable applications including at least one micro fuel cell and a microreactor, having a reaction chamber including a catalyst, for producing hydrogen gas to be fed to the micro fuel cell. The microreactor includes at least one substrate of a composite material for making printed circuits micromachined with printed circuit technology suitable for making the reaction chamber and having a semipermeable membrane on top of it. The substrate and the membrane are connected to the micro fuel cell to make a single body through a single pressure assembly step.
