PROBLEM TO BE SOLVED: To provide a hydrogen generation system capable of generating hydrogen in the immediate vicinity of a water storage portion storing water to introduce the generated hydrogen into the water of the water storage portion without disappearance of the generated hydrogen and simplify a structure thereof.SOLUTION: Counter electrodes 20 for electrolysis are provided in a chamber portion 10 provided to face an inner region of a storage water portion 90 storing water. The water in the water storage portion 90 is circulated in a chamber portion 10 to generate bubbles caused by electrolysis on each surface of the counter electrodes 20, and a water flow is positively produced between the counter electrodes 20 to remove hydrogen bubbles from the surfaces of the counter electrodes 20 and advance the hydrogen bubbles from the chamber portion 10 into the water storage portion 90. Consequently, a hydrogen generation system has a simplified structure where the hydrogen bubbles are directly introduced into the water in the water storage portion 90 from the chamber portion 10 connected to the water storage portion 90, and can be easily installed, whereby cost for introduction can be suppressed and hydrogen can reach the inside of the water storage portion 90 without being eliminated from the water to maximally maintain the hydrogen in the water of the water storage portion 90.SELECTED DRAWING: Figure 3COPYRIGHT: (C)2018,JPO&INPIT【課題】 水のある貯水部の直近で水素を発生させることで、発生した水素を消失させることなく貯水部の水中に導入できると共に、構造も簡略化可能な、水素生成システムを提供する。【解決手段】 貯水部90の水のある内側領域に面して設けられるチャンバー部10内に電気分解用の対向電極部20を設け、チャンバー部10内に貯水部90内の水を流通させて対向電極部20各表面に電気分解に伴う気泡を発生させると共に、対向電極部20間に水流を積極的に生じさせ、対向電極部20の表面から水素の気泡を離脱させてチャンバー部10から貯水部90内に進行させることから、貯水部90と一続きのチャンバー部10から貯水部90内の水に水素の気泡を直接導入する簡略な構造として、容易に設置することができ、導入のためのコストを抑えられると共に、貯水部90内に水素が水中から失われることなく到達でき、水素を貯水部90の水中に最大限保持させられる。【選択図】 図3
