摘要:
Tubular ceramic structures, e.g., anode components of tubular fuel cells, are manufactured by applying ceramic-forming composition to the external surface of the heat shrinkable polymeric tubular mandrel component of a rotating mandrel-spindle assembly, removing the spindle from said assembly after a predetermined thickness of tubular ceramic structure has been built up on the mandrel and thereafter heat shrinking the mandrel to cause the mandrel to separate from the tubular ceramic structure.
摘要:
An electrode is provided containing spherical voids which improve its gas diffusion properties and improving thermal stability of materials with different properties including the coefficient of thermal expansion. The electrode is especially useful as a component, i.e., cathode and/or anode, of solid oxide fuel cells.

Tubular ceramic structures of non-circular cross section, e.g., anode components of tubular fuel cells of non-circular cross section, are manufactured by applying ceramic-forming composition to the external non-circular surface of the heat shrinkable polymeric tubular mandrel component of a rotating mandrel-spindle assembly, removing the spindle from said assembly after a predetermined thickness of tubular ceramic structure of non-circular cross section has been built up on the mandrel and thereafter heat shrinking the mandrel to cause the mandrel to separate from the tubular ceramic structure of non-circular cross section.
