Abstract
PURPOSE:To calculate the concn. of hydrogen in a metal, by mounting an ion conductive solid electrolyte to a metal and converting the hydrogen stream diffused and transmitted through the metal to the ionizing current to a solid electrolyte. CONSTITUTION:The hydrogen dissolved in the metal of piping as a solid solution transmits to the outside and is oxidized to a proton by a detection electrode 4 and the generated proton moves to an opposed electrode 8 because of the low hydrogen concn. in a cover 12. The electron generated in the detection electrode 4 flows to the opposed electrode 8 from an ammeter 18 through a power source 16 with the oxidation of hydrogen to the proton. The proton and the electron are again bonded in said opposed electrode 8 to be discharged as a hydrogen molecule or steam along with an Ar stream. Herein, the current flowing through the ammeter 18 is equal to the proton current in a conductor 2 and equal to the transmission speed of hydrogen if there is no side reaction in the detection electrode 4. The transmission speed of hydrogen is proportional to the concn. of hydrogen in the metal of the piping and divided by the hydrogen diffusion constant of the metal of the piping to make it possible to obtain the concn. of hydrogen in the metal.
