なっている。FIG. 4 is a sectional view showing a closed control panel as a conventional electrical device disclosed in, for example, Japanese Patent Application Laid-Open No. 57-49305. In the figure, (1) is a casing that houses electrical components (2) inside, (1a) is a door provided on the - side of the sieve body (1), and (3) is a door provided all around the door (1a). Airtight gaskets attached to each other, (4) is an adsorption/humidity absorber containing a gas adsorbent and a moisture absorbent inside, +51 (61 is an air pump and its driving power supply; this adsorption/humidity absorber (4) and the air pump (5) means valves (
8) to communicate with the inside of the unit (1). The casing (1) has a sealed structure without a ventilation opening to prevent moisture and corrosive components from entering the outside air.

吸着する。この動作を所定時間継続することによって、
筐体（１）内の湿気や腐食性ガスは十分に除去されるこ
とになる。Next, the operation will be explained. The air pump (5) is driven by the power source (6), and the air inside the housing (1) is pumped through the piping (
7a), passes through the adsorption/humidity absorber (4), and returns to the housing (1) through the piping (7b). This results in
The gas adsorbent housed in the adsorption/hygroscopic device (4) adsorbs corrosive components in the air passing through it, and the moisture absorbent adsorbs moisture in the air. By continuing this operation for a predetermined time,
Moisture and corrosive gas within the housing (1) will be sufficiently removed.

吸着吸湿器（４）内の吸着剤や吸湿剤は長期間使用する

その吸着、吸湿能力が低下していくので、定期的にこれ
ら吸着剤、吸湿剤を新しいものと交換する必要がある。Conventional sealed control panels are configured as described above.
If the adsorbent or moisture absorbent in the adsorption/moisture absorber (4) is used for a long period of time, it will adsorb corrosive gases and moisture, increasing their concentration, and gradually decreasing their adsorption and moisture absorption ability, so they should be periodically removed. It is necessary to replace the moisture absorbent with a new one.
また、筐体（１）内の空気を吸着吸湿器（４）に強制的
に循環させるためエアーポンプ（５）のような回転機構
部を有する部品を使用しているので、その保守管理も必
要となり省力化の要請に反するという問題点があった。In addition, since parts with rotating mechanisms such as the air pump (5) are used to forcefully circulate the air inside the housing (1) to the moisture absorption device (4), maintenance of these components is also required. Therefore, there was a problem that it went against the demand for labor saving.
上記した吸湿能力の低下を補う意味で、筐体（１）内に
スペースヒータを設置し、筐体（１）内の温度を外気温

３に対し約Ｑ、５ｋｗ程度のものが必要となる。従って
、変電所のように、多数の密閉制御盤が設置されるよう
な場合には、このスペースヒーターのために大量の電力
が消費されるという問題点があった。In order to compensate for the above-mentioned decrease in moisture absorption capacity, a space heater is installed inside the housing (1) to maintain the temperature inside the housing (1) about 5°C higher than the outside temperature. In some cases, a method is adopted to lower the relative humidity and suppress the occurrence of condensation inside the housing (υ). However, in this case, the capacity of the space heater is the volume of 1 m inside the housing (1).
For 3, approximately Q, 5kw is required. Therefore, in a case where a large number of closed control panels are installed, such as in a substation, there is a problem in that a large amount of electric power is consumed for this space heater.
更にまた最近、例えば小型の固定礎気ディスク装置のよ
うに、内容積が数百（１６程度の比較的小容積の装置内
の除湿を行うため、固体電解質を用いた除湿器を適用し
ようとする試みがなされている。Furthermore, recently, attempts have been made to apply dehumidifiers using solid electrolytes to dehumidify devices with relatively small internal volumes of several hundred (16 or so), such as small fixed basic air disk devices. Attempts are being made.
しかし、これらの装置に使用される固体電解質は表面積

２以上もある筐体の内部の除湿を行うには、１００個程
度の上記除湿器を一つの筐体に並設する必要がありその
取付スペースや配線が極めて複雑になり信頼性も低下せ
ざるを得ない。However, the solid electrolyte used in these devices has a surface area of 1 to several am' at most, and the internal volume of the device that can dehumidify is limited to about several hundred square meters. Therefore, in order to dehumidify the inside of a case with an internal volume of several dozen or more, such as a control panel or current collector board installed in a substation or power plant, approximately 100 of the above dehumidifiers are required at once. They must be installed in parallel in one housing, making the installation space and wiring extremely complicated, and inevitably lowering reliability.

に形成される多孔性電極は通常数μｍ程度の厚さに過ぎ
ず、その表面抵抗が大きいため電流分布が極めて悪く所
望の除湿能力が得られないという問題点があった。In order to prevent this problem, it is conceivable to significantly increase the surface area of the solid electrolyte in each dehumidifier in accordance with the required dehumidification capacity. However, the porous electrode formed on the surface of the solid electrolyte is usually only a few micrometers thick and has a large surface resistance, resulting in extremely poor current distribution and the inability to obtain the desired dehumidifying ability. .

目的とする。This invention was made to solve the various problems mentioned above, and it is possible to dehumidify a large-volume case with relatively low power, and it can be used semi-permanently without maintenance. The aim is to obtain an electrical device with a possible dehumidification mechanism.

It has a source.

記した除湿の反応は除湿器の全域でほぼ均等に行われ、
効率のよい除湿が達成される。Due to the presence of the feed electrode, the distribution of current flowing through the dehumidifier is approximately evenly distributed over the area of the electrode. Therefore, the dehumidification reaction described above takes place almost uniformly throughout the entire area of the dehumidifier.
Efficient dehumidification is achieved.

) (12b) is a porous electrode of platinum or nickel formed by voltageless plating on both the front and back surfaces of the proton conductive solid membrane (b), and the film thickness is suitably about 1 to 3 μm. If this film thickness is too thin, the electrical resistance will increase and it will not be possible to conduct electricity sufficiently. Furthermore, if the thickness of the plating film is too thick, the porosity will decrease, and the proton conductive solid membrane (b) will not come into sufficient contact with air, resulting in a decrease in dehumidifying ability. Then, a proton conductive solid membrane (b) and a porous electrode (12 m

The above current is almost uniformly diffused over the entire electrode surface of the feeding electrode (13a), and from this state it spreads between the porous electrode (12m) and the proton conductive solid film α to the porous electrode (12b). direction and reaches supply iii (13b).
ここで再び面と平行な方向に流れ、リード線（至）に集

The inside of the housing (1) is dehumidified.The porous electrode (12aM
12t+) has an extremely large area compared to its thickness, and the current distribution when used alone is extremely poor, but here, feeding electrodes (13a) (13b) are newly provided, so Due to the above-mentioned single effect, the current flows almost uniformly over the entire surface, resulting in highly efficient dehumidification. Moreover, this dehumidification effect is performed semipermanently as long as the electricity continues.
