Permeation study
WebThe variables considered in the systematic permeation study included the inlet gas flow rate of the sweep and air feed, the temperature and the nature of the oxygen feed gas (air or pure oxygen). Moreover, the influence of the deposition of a catalytic activation layer (17 μm thick) made of BSCF on top of the thin gastight layer was investigated.
