The patent adopts the phenomenon that water changes into hydrogen when a concentration difference dialysis battery generates electricity, and provides a new electricity generation method and a new electricity generation mode for the utilization of hydrogen energy. For example: the structure of the hydrogen energy generator is a hydrogen energy generating system comprising a hydrogen production device and a generating device, a hydrogen producing agent is adopted to react with water instantly to produce hydrogen, and the produced hydrogen is used in a hydrogen energy utilization mode of generating electricity in a fuel cell, thereby providing a new application approach for the application of hydrogen energy. The two hydrogen production and power generation modes have the defects of low hydrogen production efficiency and low power generation.
