| description | A nickel purifier and a hydrogen frequency standard are disclosed. The nickel purifier includes a quartz tube; a spiral nickel tube disposed in the quartz tube; two ceramic tube segments symmetricallysleeving the quartz tube, with the two ceramic tube segments being spaced apart to form a gap; a hydrogen feeding connector spanning the gap and connected to the peripheries of ends, close to each other, of the two ceramic tube segments, with the hydrogen feeding connector being connected to a hydrogen feeding passage; two hydrogen feeding heads each of which is symmetrically connected to the other end of the corresponding ceramic tube segment; and two one-way welded sheets symmetrically connected to the two hydrogen feeding heads respectively. The nickel purifier adopts an axially symmetrical structure design, and an original ground terminal achieves insulation of two electrodes through two ceramic parts, thus radically avoiding a situation that negative-terminal current flows through aphysical part of the hydro |
