The Rolls-Royce plan was mapped out at the Seventh Grove Symposium (Agnew 2001), and is based on optimisation of the current, all-ceramic design as part of a gas turbine hybrid. The Rolls-Royce gas turbine will be optimised for hybrid service. The potential of its fuel cell, for cheapness via mass production, is stressed in its patents. Capital costs could come down to 300/kWe. There are no signs up to 2005 of a Rolls-Royce ITSOFC waiting in the wings. 

A special stainless steel was developed in Australia and patented (Jaffray, 1999). Production costs and endurance of the resulting flat plate design (Foger etal, 2000) were improved relative to that of the firm s initial all-ceramic design. The bipolar plates and interconnects were stainless steel. The cell had operational difficulties, and has been discontinued. The firm has just established a UK division, to compete in Europe.

Clearly, the extensive use of ceramics will lead to the development of increasingly sophisticated structures, including extensively nanostructured materials. Moreover, the benefits of ceramic design will lead to new scientific challenges, creating new structural and functional applications. Despite the world of ceramics superplastidty being born over twenty years ago, its transition from childhood to maturity remains an ongoing process. 

Regardless of whether a material is metallic or ceramic, design to overcome fatigue failure and to increase resistance to cyclic deformation is essential. However, for the time being, this task seems almost impossible. As indicated...

In an attempt to marry the best characteristics of HTCC and LTCC, Kyocera has developed an intermediate-firing cofired ceramic, designated as A0600. This alumina material employs copper-based conductors. Thus, this composition enjoys the low electrical resistivity of Cu metallization along with the superior mechanical and thermal properties of alumina. A "broad-brush" comparison of this material to standard 92% alumina and a generic LTCC formulation is presented in Table 6.4.
