摘要： A hydrogen patch cell for measuring hydrogen atoms produced in the corrosion of ferrous metals. The cell mounts on the diffusion side of a ferrous wall being penetrated by hydrogen atoms and comprises a body having a cavity enclosed by an insulating impervious material. An electrolyte in the cavity provides an environment for the conversion of hydrogen atoms to ions. An end portion of the body carries a fluid-tight seal to the ferrous wall. An inert barrier within the body adjacent the end portion interposes between the cavity and the ferrous wall, adjacent to the wall. The barrier is permeable to hydrogen atoms but impermeable with respect to the electrolyte. A coupling material fills the void between the barrier and the ferrous wall and this material is inert but permeable to hydrogen atoms. Electrodes on the body connect to external circuitry for the electrochemical conversion of hydrogen atoms to ions which enter the electrolyte. One electrode in the electrolyte is a planar metal electrode coextensive with the barrier.
