Progress in the Development of a Low Cost 1MW SOFC Hybrid

Rolls-Royce Fuel Cell Systems (RRFCS) is developing a low cost 1MW fuel cell hybrid system package, supported by a prototype demonstration of a 250kW module in 2006. This paper describes the detailed design process that has been carried out to produce the fuel cell stack, tailored turbo-machinery and other plant components for this hybrid. Progress in demonstrating components is described. Component interfacing, operability and control challenges have been assessed prior to assembly of the complete system and are reviewed. The baseline plant will be highly efficient compared to incumbent power generation technologies but is primarily optimised around cost-reduction. Evolution of the product will include opportunities for further increases in efficiency and power density. Opportunities for improvement are discussed.
