NOVELTY - Portable hydrogen generator based on aluminum hydrolysis reaction, comprises an U-shaped stainless steel pot body with hollow inner wall and a cover body. The pot body is divided into a heat exchanging chamber, an alloy storage chamber, a separation film and a hydrogen storage chamber from bottom to top. The heat exchanging chamber is a hollow body between the inner wall and outer wall of the pot body. The separation film is a compact foamed nickel adhered by a hollow ring. The inner part of the pot body is divided into an alloy storage chamber and a hydrogen storage chamber.    USE - Used as a portable hydrogen generator based on aluminum hydrolysis reaction.    ADVANTAGE - The device: is simple, safe and reliable; has excellent controllability; does not need electricity; discharges stable output hydrogen pressure; effectively controls the generating speed of the hydrogen; and is suitable for multiple fuel batteries.    DETAILED DESCRIPTION - Portable hydrogen generator based on aluminum hydrolysis reaction, comprises an U-shaped stainless steel pot body with hollow inner wall and a cover body. The pot body is divided into a heat exchanging chamber, an alloy storage chamber (i.e. reaction area), a separation film and a hydrogen storage chamber from bottom to top. The heat exchanging chamber is a hollow body between the inner wall and outer wall of the pot body. The separation film is a compact foamed nickel adhered by a hollow ring. The inner part of the pot body is divided into an alloy storage chamber and a hydrogen storage chamber. The inner wall of the pot body is adhered with a water inlet columnar tube, where the surface of the columnar tube is distributed with even small holes, and the top end is connected with the heat exchanging chamber by the capillary tube. The heat exchanging chamber is fixedly connected with the water injecting tube. The water injecting tube is vertical to the horizontal plane, and is connected with outside. The water injecting tube is provided with threads and controls the water inlet pressure by rotating the nut.    DESCRIPTION OF DRAWING(S) - The drawing shows a schematic representation of the portable hydrogen generator based on aluminum hydrolysis reaction.
