Rolls-Royce has experience in the system integration of several different types of fuel cells and believes the Solid-Oxide Fuel Cell is the best for stationary power generation applications while retaining the capability of being developed subsequently for various transportation, military and marine applications.

The fuel cell is produced by screen printing on low cost ceramic type materials using proven production processes and minimal exotic materials.
Low cost

The system uses commercial-grade materials, has few components and is low in weight.
Efficiency

Nearly double the simple-cycle efficiency of existing power generation technologies.
Profile

Size and weight suitable for distributed generation with potential for power densities equivalent to gas turbine systems.
Environment

Negligible air emissions, minimal noise profile and can be entirely recycled at the end of its useful life.
Maintainability

Unique, modular design enables field change-out without interruption of supply and enhanced support through state-of-the-art diagnostic and prognostic systems.
Safety

Low parts count and the elimination of low durability components gives a realistic design target of 40,000 hours operation on a mature product and a 20-year 160,000 hour overall plantlife potential.
Fuel flexibility

System can be configured to use existing hydrocarbon-based fuels, i.e. natural gas and liquid fuels, and alternative fuels such as coal gas and bio-mass.
Security

Suitable for connection to local distribution networks and in small, secure urban areas.
