摘要

In this paper we present a model for hydrogen permeation for proton-conducting ceramic membranes based on the ambipolar diffusion theory. A general equation is derived which correlates the hydrogen permeation flux to the concentrations and diffusion coefficients of multiple charged species. The equation can be further simplified into analytic expressions relating the hydrogen permeation flux to the hydrogen partial pressures at the upstream and downstream sides for special cases. The results of the theoretical model are compared with experimental hydrogen permeation data of a proton conducting ceramic membrane. Good agreement between the model and experimental data is obtained.
