[0036] Preparation of dense oxygen permeable layer slurry. Oxygen ion conductor powder, electron conductor powder, dispersant, binder, plasticizer and solvent are ball-milled and mixed to prepare a dense oxygen-permeable layer slurry. In an optional embodiment, the dispersant can be triethanolamine, acrylic resin, methyl amyl alcohol and acrylic acid copolymer, etc., and the added amount is 4-6% of the total mass of the oxygen ion conductor powder and the electron conductor powder. In an optional embodiment, the binder can be polyvinyl butyral, epoxy resin, polypropylene resin, etc., and the amount added can be 10-12% of the total mass of the oxygen ion conductor powder and the electron conductor powder . In an optional embodiment, the plasticizer can be dibutyl phthalate, polyethylene glycol, benzoate, etc., and the amount added can be 5-5% of the total mass of the oxygen ion conductor powder and the electron conductor powder. 7%. In an optional embodiment, the solvent may...
