TECHNOLOGY FOCUS - CHEMICAL ENGINEERING - Preferred Vessel: The reactor vessel further comprises an agitating means arranged within the reactor vessel. Agitating means is a screw. It is rotatably mounted within the reactor vessel. The material of the agitating means is an anti-corrosive material. The anti-corrosive material is a thermoplastic polymer, where the thermoplastic polymer is selected from polystyrene, polyphenyl ether, polyethylene terephthalate, polyvinyl chloride, polyetheretherketone, polyethersulfone, polyphenyl sulfide, polyethylene sulfone, polyimide, polyphenylene sulfide and its combinations. The thermoplastic polymer is polyetheretherketone. The third inlet is in fluid communication with water storage means. The water storage means is in fluid communication with a container for storing the reaction mixture, where the reaction mixture is obtained from the reactor vessel via at least one outlet of the reactor vessel, thereby enabling the container to feed water from the water storage means back into the reactor vessel. The reactor vessel also comprises a condenser arranged between the water storage means and the container. The catalyst precursor material is present in the form of a solution; or the catalyst precursor material is a metal salt, where the metal salt is selected from metal chloride, metal sulfate, metal acetate, metal nitrate and its combinations. Metal salt is selected from cobalt chloride, cobalt sulfate, cobalt acetate, nickel acetate, nickel chloride, nickel sulfate, ruthenium chloride, ruthenium nitrosyl chloride, ruthenium nitrosyl nitrate, platinum chloride and its combinations. The hydrogen precursor material is a metal hydride, where the metal hydride is selected from sodium borohydride, lithium borohydride, potassium borohydride, ammonium borohydride, calcium borohydride, magnesium borohydride, tetramethyl ammonium borohydride, and its combinations. Hydrogen precursor material is present in an alkaline solution, where the alkaline solution comprises sodium hydroxide, lithium hydroxide, potassium hydroxide, ammonium hydroxide and/or its combinations. The pitch length of the screw is about 8 mm to about 16 mm. The reactor vessel further comprises at least one outlet for removing the reaction mixture from the reactor vessel, where the reaction mixture is produced by the hydrogen generation reaction. The reaction mixture comprises hydrogen and by-products of the reaction. Preferred Method: Generating hydrogen further comprises separating the water from the generated hydrogen gas stream, upon removing the reaction mixture from the reactor vessel. Separating comprises condensing the water via a condenser. The method also comprises feeding the condensed water back into the reactor vessel. Catalyst is a metal boride, where metal boride is a Group VIII metal boride. The metal boride has a general formula of CoxBy, where x is an integer of 2 or 3, and y is an integer of 1. Preferred System: In the system, the reaction mixture comprises hydrogen and byproducts. The system further comprises a dryer for separating the hydrogen from the reaction mixture. Hydrogen is supplied to a fuel cell module. EXAMPLE - No suitable example given.
