Beschreibungen/Notizen

• An inexpensive approach for depositing 4 to 10 mu m electrolyte films onto porous electrode supports in a single step is described. This approach involves the use of colloidal dispersions of polycrystalline electrolytes. This technique leads to highly dense, conductive, electrolyte films which exhibit near theoretical open circuit voltages in H sub(2)/air fuel cells. These electrolyte films exhibit bulk ionic conductivity, and may see application in reduced temperature solid oxide fuel cells (SOFCs), gas separation membranes, and fast response sensors.
