A microbubble generator for a hydrogen generating device and a microbubble generating device comprising the same, the microbubble generator comprising a housing and a microbubble generating unit. In addition, the microbubble generating device comprises a microbubble generator, a fluid driving unit and a fluid pressurizing unit, and the fluid pressurizing unit is connected to the microbubble generator, and the fluid driving unit is connected to the fluid pressurizing unit and is used for connecting the hydrogen supply unit and the water supply unit. Thereby, the present invention allows hydrogen and water to be mixed by the fluid driving unit and then pressurized by the fluid pressurizing unit, and then output through the microbubble generator to effectively increase the content of hydrogen dissolved in water.一種產氫裝置之微泡產生器及包含其之微泡產生裝置，微泡產生器包含殼體及微泡產生單元。另外，微泡產生裝置包含微泡產生器、流體驅動單元及流體加壓單元，流體加壓單元連接微泡產生器，流體驅動單元連接流體加壓單元並用以連接氫供應單元與水供應單元。藉此，本發明可讓氫與水由流體驅動單元混合後再以流體加壓單元加壓，之後經由微泡產生器輸出，以有效提高氫溶於水之含量。
