LG Fuel Cell Systems (LG), formerly Rolls-Royce Fuel Cell Systems, will lead a team to develop low cost solid oxide fuel cell (SOFC) technology for use in highly-efficient and technologically-integrated central generation power plant facilities fueled by coal synthesis gas. The project consists of three elements, cost reduction research and development (R&D), systems R&D, and a manufacturing element. The project will utilize LG’s proprietary segmented-in-series SOFCs at pressures up to seven atmospheres. These cells are created by screen-printing the active cell layers (anode, cathode, and electrolyte) onto ceramic flat substrates. Each ceramic flat substrate contains a large number of small planar cells connected in series (segmented-in-series design).
LG’s plan is to reduce SOFC-based electrical power generation system cost; to achieve an overall integrated gasification fuel cell power plant efficiency of 50 percent or more; to reduce the release of CO2 to less than 10 percent of the carbon in the coal feed-stock; and to increase SOFC stack reliability.
