HYDROGEN SENSOR |
摘要 |
A gas sensor suitable for measuring hydrogen concentration, including a proton conductive layer (1); a first electrode (3) and a second electrode (5) provided on the proton conductive layer (1); a gas diffusion-limiting inlet (19) provided between the first electrode (3) and a measurement gas atmosphere (6) containing hydrogen gas; and a gas diffusion-limiting outlet (21) provid ed between the second electrode (5) and the atmosphere (6); wherein the ratio (a/b) between the diffusion resistance (a) of the diffusion limiting portion (19) and the diffusion resistance (b) of the gas outlet portion (21) is not great er than
