NOVELTY - Controlled production of continuous flow of hydrogen involves: (a) adding a fuel solution to a reactor at a constant rate, the solution comprises 9-19% w/w of complex hydride stabilized in a hydroxide, on a catalyst of cobalt and boron (Co-B) supported on a stainless steel monolith, where the catalyst is located inside the reactor in an excess quantity of 37-240 mg; (b) catalytically hydrolyzing the complex hydride, and generating a continuous flow of hydrogen; and (c) continuously removing the products of the catalytic hydrolysis in the form of molten salt.    USE - The process is useful for controlled production of continuous flow of hydrogen. The continuous flow of hydrogen is useful for producing energy, where energy production is performed by a fuel cell. The steel monolith is useful as a catalyst support for the process (all claimed). The process is preferably useful for generating hydrogen-rich gas streams by hydrolysis, particularly hydrides, and more particularly complex hydrides which can be used in hydrogen production plants, combustion engines and particularly to fuel cell systems.    ADVANTAGE - In controlled production of continuous flow of hydrogen, the catalyst support meets maximum fill volume of the reactor, thus takes full advantage of the entire volume and prevents preferential paths of the reagents, so as to maximize conversion. The complete design (reactor and supported catalyst) can produce a steady stream of hydrogen without increases in the production rate. The catalyst is stable throughout the system operation. The catalyst can be reused in an experience similar to the initial or at different conditions, without loss of efficiency, that is, without reducing the production rate of hydrogen. It allows recycling as many times as possible without loss of efficiency or deactivation.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) a device for carrying out the process, comprising a storage tank for fuel settlement; a continuous reactor; dispensing unit of the solution within the continuous reactor; separator tank of the hydrogen stream and the products of hydrolysis; and drying unit of the hydrogen stream separated in the separator tank; and    (2) steel monolith suitable for use as a catalyst support of the process, where the monolith is made from the process comprising at least one stage of heat treatment and machining to improve the adhesion of the catalyst.
