There are conventional methods for being sealed in an aluminum pack, an aluminum bottle, or a PET bottle, refining for generating hydrogen, or being generated by using a hydrogen generating material in the form of a rod, fixing an electrode inside a port and then generating hydrogen water, inserting and holding an electrode and then generating hydrogen water, or the like. However, depending on a problem of hydrogen penetrability, a hydrogen concentration is declined by long-term storage from a manufacturing step, or it is difficult to transfer or move in a case of a port type or a mount type or the like. Moreover, there are problems to be solved that the time is required for generating hydrogen water； a hydrogen concentration is low； or the service life of an electrode is short. Moreover, a user checks a concentration by using a separate hydrogen concentration measuring device so as to measure an actual hydrogen concentration. According to the present invention, due to being small and lightweight, the device can be used at home, transferred, and moved. Moreover, a certain concentration of hydrogen water is generated in a short time according to power amplification. When two stages are selected in response to the amount of generated water, conversion of a positive electrode and a negative electrode is possible. Moreover, the device has a structure capable of reducing load of an electrode. As a part of a relative distance to be replaced by using both of a positive electrode and a negative electrode is reduced, the hydrogen generation amount is increased under water, and an actual hydrogen concentration can be measured by the user at the same time.본 발명은, 알루미늄 팩이나 알루미늄병, 페트병에 봉입된 것, 또한 수종에 있어서 수소를 발생시키는 정제나, 봉상의 수소발생소재를 이용하여 생성하는 것, 포트 내에 전극을 고정하여 수소수를 생성하는 것, 전극을 삽입 유치하여 수소를 생성하는 것 등이 있으나, 수소투과성의 문제에 따라 제조단계로부터의 장기간 보관에 따른 수소농도의 감퇴나, 포트식 또는 거치식 등은 운반이나 이동이 곤란하며, 또한 수소수 생성에 시간을 요하고, 수소농도가 낮은 것이나, 전극자체의 수명이 짧은 점 등 개선할 과제가 있고, 또한 사용자가 실제의 수소농도를 측정하기에는 별도 수소농도측정기를 이용하여 확인하
