PRODUCTION OF POROUS CERAMIC ELECTRODE

摘要

PURPOSE:To form a porous electrode excellent in gas diffusibility and electrical conductivity. CONSTITUTION:A slurry 8 composed of a perovskite-type compound oxide having a particle size adjusted to a suitable value is put in a vessel 7 and a porous substrate 2 is then immersed therein for a sufficiently long time while uniformly stirring the slurry 8 by rotating a magnetic bar 9 using a stirrer 10. An uncalcined perovskite-type compound oxide layer is formed on the surface of the porous substrate 2 and film formation is carried out after sufficiently drying the resultant layer in a condition where cracking can be prevented by calcining the dried layer, thus obtaining the objective porous electrode.
