  • Description:This project is aimed at preparation of thin (1-10? m) membranes of a modified strontium ceramic material with improved hydrogen permeance on mesoporous substrates. The research work conducted in this reporting period was focused on the following three aspects: (1) preparation of thick proton-conducting ceramic membranes and synthesis of porous substrates as support for thin proton-conducting ceramic film, (2) setting up RF sputter deposition unit for deposition of thin ceramic films and performing deposition experiments with the sputter deposition unit, and (3) modeling hydrogen permeation through the proton-conducting ceramic membranes. Proton-conducting thulium doped strontium cerate membranes were reproducibly prepared by the citrate method. Mesoporous ceria membranes were fabricated by a sol-gel method. The membranes will be used as the substrate for coating thin strontium cerate films. A magnetron sputter deposition unit was set up and good quality thin metal alloy films were formed on the mesoporous substrates by an alternative deposition method with the sputter deposition unit. A theoretical model has been developed for hydrogen permeation through proton conducting ceramic membranes. This model can be used to quantitatively describe the hydrogen permeation data. ...Show Less
