A method is described for quantitative measurement of the hydrogen flux through protonic ceramic hydrogen separation membranes under practical operating conditions. The method uses a simple stoichiometric titration technique to determine the quantity of oxygen required in the membrane permeate stream to reach the lambda transition point, as determined by a down-stream zirconia oxygen sensor. As such, the method does not require the use of gas chromatographs or mass spectrometers, which are difficult to calibrate for hydrogen under high pH2O conditions. The theory of operation and application to yttrium-doped barium cerate/zirconate, BCZY, membranes is laid out in detail in consideration of the unique transport properties of these perovskite proton conductors under galvanic operation in asymmetric atmosphere conditions. The Faradaic efficiency toward hydrogen in these membranes was found to be 95% at 700°C, and the H2 flux was 1.4sccm/cm2 (0.95μmol/scm2) when pumped galvanically at 8V. © 2014 The Authors. Source

A model-based interpretation of measured equilibrium conductivity and conductivity relaxation is developed to establish thermodynamic, transport, and kinetics parameters for multiple charged defect conducting (MCDC) ceramic materials. The present study focuses on 10% yttrium-doped barium zirconate (BZY10). In principle, using the Nernst-Einstein relationship, equilibrium conductivity measurements are sufficient to establish thermodynamic and transport properties. However, in practice it is difficult to establish unique sets of properties using equilibrium conductivity alone. Combining equilibrium and conductivity-relaxation measurements serves to significantly improve the quantitative fidelity of the derived material properties. The models are developed using a Nernst-Planck-Poisson (NPP) formulation, which enables the quantitative representation of conductivity relaxations caused by very large changes in oxygen partial pressure. © The Royal Society of Chemistry.

A sintered ceramic ball is described that includes an incomplete ceramic ball portion with a wall with an exterior surface, the wall having an interior space located radially interior of an inner surface of the wall. The incomplete ceramic ball portion also has an exterior surface, the exterior surface having an exterior surface area. The sintered ceramic ball further includes a ceramic plug joined with the incomplete ceramic ball portion to form a continuous exterior ball surface. The ceramic plug includes an exterior plug surface and a plug wall. The plug surface includes an exterior plug surface area, wherein the exterior plug surface area is between about 5% to 49.9% of the sum of the exterior surface area of the incomplete ceramic ball portion and the exterior plug surface area. The interior space of the sintered ceramic ball is sealed within the wall and the plug wall.
