The invention discloses a hydrogen aluminum metal complex. Relative to 100 parts of aluminum powder by weight, the complex also comprises 0.1 to 0.3 part of gamma-Al2O3, 0.1 to 0.5 part of a peroxide initiator, 4 to 20 parts of an adhesive and 15 to 25 parts of a slow-release agent. According to the invention, the aluminum powder and a dispersant are utilized to constitute a uniform hydrogen-producing complex with the gamma-Al2O3, the initiator, the adhesive and the slow-release agent; the phenomenons of excessively high reactor temperature and excessively large pressure due to excessively rapid disintegration speed of a conventional complex in the process of high-temperature hydrogen production are solved; only one metal powder, i.e., the aluminum powder, is adopted; in the process of a reaction, the aluminum powder is one of the main factors of improving electrons and forming hydrogen, and the byproduct of the aluminum powder can also continuously supply a catalyst namely the gamma-Al2O3 for water-vapor hydrogen production; thus, the reaction continuity is improved, and the yield of hydrogen is further increased.
