Abstract
Oxygen transport in an LSM/YSZ/LaAlO solid oxide fuel cell type reactor was studied. The oxygen permeation flux was 8.90 × 10 −8 mol m −2 s −1 at 1173 K with an activation energy of 170 kJ mol −1. By applying an external potential, the oxygen permeation flux increased while the activation energy of oxygen permeation decreased. The oxygen permeation fluxes under methane feed in the anode side are 1–2 orders of magnitude higher than those under helium feed. A model of oxygen permeation was presented and the permeation parameters were proposed. In the case of helium feed, the oxygen permeation at the LaAlO anode was the rate-limiting step. However, changing helium to methane as a reactive gas, the resistances for the oxygen permeation in the three parts (LSM/YSZ/LaAlO) were comparable.
