The present invention relates to a method for promoting the dehydrogenation reaction of ammonia borane pellets comprising a solid catalyst, comprising the steps of: preparing a mixture by mixing ammonia borane and a solid catalyst; Pelletizing the mixture to produce an ammonia borane pellet; Feeding the prepared ammonia borane pellets to a reactor; And a hydrogen production step of accelerating a dehydrogenation reaction by applying heat to the reactor to which the ammonia borane pellet is supplied. The hydrogen production step not only promotes the rate of hydrogen generation but also achieves continuous hydrogen generation.
