素を生成する水素発生装置に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention is directed to a solid polymer electrolyte (Solid Polymer Electrolyte).
yte (hereinafter abbreviated as SPE)), and relates to a hydrogen generator that produces hydrogen by electrolyzing water.
特に、水素を1.5〜５気圧程度の圧力下で、ガスクロマ
トグラフのキャリヤーガス源、水素炎イオン化検出器の
燃料ガス源として利用する場合に好適な水素発生装置を
提供するものである。In particular, the present invention provides a hydrogen generator suitable when hydrogen is used as a carrier gas source for a gas chromatograph and a fuel gas source for a hydrogen flame ionization detector under a pressure of about 1.5 to 5 atmospheres.
（従来の技術） SPEセルを使用する水素発生装置は、例えば実公昭62-17
486号で既に知られている。(Prior Art) A hydrogen generator using an SPE cell is disclosed, for example, in Japanese Utility Model Publication No. 62-17.
It is already known by issue 486.

従来装置の流路構成に基づき説明する。However, in the conventional device, there is a risk that oxygen gas generated in the anode chamber of the SPE cell and hydrogen gas generated in the cathode chamber are mixed in the water tank and explode. This will be described based on the flow path configuration of the conventional device shown in FIG.

器23、水・水素分離容器15はこれ以上の圧力となる。A DC voltage is applied to the SPE cell 11, water is electrolyzed, and hydrogen gas is generated in the cathode chamber 13 and oxygen gas is generated in the anode chamber 12, respectively. Due to the characteristics of the SPE cell, the generated hydrogen gas moves to the water / hydrogen separation container 15 together with a small amount of water that moves from the anode chamber 12 to the cathode chamber 13, and passes through a dryer 23 filled with silica gel particles and the like. Adjusted to a predetermined pressure by pressure regulator 25,
Take exit 27. On the other hand, the water separated in the water / hydrogen separation container 15 is returned to the water tank 19. When hydrogen gas is used as a carrier gas for a gas chromatograph, an outlet pressure of about 4 atm is required, and the dryer 23 and the water / hydrogen separation container 15 upstream of the pressure regulator 25 have higher pressures.
水タンク19は、排水路21を通り水と一緒に戻る酸素ガス
を流路外に放出するため、大気に開放された出口３を有
している。The water tank 19 has an outlet 3 that is open to the atmosphere so as to discharge the oxygen gas that passes through the drainage channel 21 and returns together with water to the outside of the flow path.
ところで、ヘンリーの法則として知られているように、

合される。このため、上記した爆発の危険性が生ずる。By the way, as known as Henry's Law,
The degree to which a gas dissolves in a liquid is proportional to the partial pressure of the gas. The water in the water / hydrogen separation container 15 is in equilibrium with the high-pressure hydrogen gas and dissolves the hydrogen gas. Therefore, the hydrogen gas is gradually decompressed while passing through the flow path 18, the hydrogen gas is separated, and mixed with the oxygen gas returning via the drainage path 21 in the water tank 19. Therefore, the above-mentioned danger of explosion occurs.

A DC voltage is applied to the SPE cell 11, water is electrolyzed, and hydrogen gas is generated in the cathode chamber 13 and oxygen gas is generated in the anode chamber, respectively. The generated hydrogen gas, along with the characteristics of the SPE cell, together with a small amount of water that moves from the anode chamber 12 to the cathode chamber 13,
It is led to the water / hydrogen separation container 15. In the water / hydrogen separation container 15, hydrogen gas is separated above the container and water is separated below the container due to the difference in weight. The hydrogen gas is further removed of mixed water vapor in the dryer 23, regulated to a predetermined pressure by the pressure regulator 25, and supplied to a gas chromatograph or the like connected to the hydrogen gas outlet 27.

衝撃を与えることにより効果的に行うことができる。Water accumulated in the lower part of the water / hydrogen separation container 15 moves to the hydrogen separation container 1 having the outlet 2 open to the atmosphere by the operation of the solenoid valve 17 which is opened / closed by a signal from a water surface detection means (not shown) or the like. Hydrogen gas dissolved in water is separated from water by
It is released into the atmosphere through outlet 2. That is, since the amount of hydrogen gas dissolved in water in the container is determined by the equilibrium state with the atmosphere, most of the hydrogen gas dissolved in water is released to the atmosphere, and the water no longer contains hydrogen gas. . The separation and release of hydrogen gas can be effectively performed by applying a mechanical shock with a means such as a rotor and ultrasonic waves.
