Description
(実施形態1)本実施形態の水素センサは、図1に示すように、水素が接触する測定電極1bを下面に備え、基準ガスが接触する基準電極1cを上面に備える固体電解質素子1と、固体電解質素子1の外周を保護するキャップ2と、を有している。
濃淡電池の原理より、この電池の理論起電力は、基本的には下記のネルンストの式で表される。
K=RT/(2F) (3)
ここで、E:起電力、P1:被測定物質中の水素分圧、P2:基準ガス中の水素分圧、R:気体定数、T:絶対温度、F:ファラディ定数、である。
(実施例1)本実施例の水素センサは、図2に示すように、断面U字状(有底筒状)の固体電解質10aの外周面に測定電極10bが形成され、内周面に基準電極10cが形成された固体電解質素子10の上部にアルミナチューブ30が取り付けられてなる。
1a、10a・・・・・測定電極
1b、10b・・・・・基準電極
2、20・・・・・・・キャップ
Claims (2)
- 水素が接触する測定電極を一方の面に備え基準ガスが接触する基準電極を他方の面に備える固体電解質素子と、前記固体電解質素子の外周を保護するキャップと、を有する水素センサであって、
前記キャップはカーボンからできておりかつ前記キャップは水素が通過する通孔を有し、前記通孔には液体の浸入を抑制する多孔質体を有することを特徴とする水素センサ。 - 前記カーボンがグラッシーカーボンである請求項1に記載の水素センサ。
