Solid Oxide Fuel Cell Stack Module Development for Fuel Flexible Power Generation

FuelCell Energy is developing solid oxide fuel cell (SOFC) systems and technology for very efficient, economically viable, coal-to-electricity power plants utilizing synthesis gas (syngas) from a coal gasifier for the Department of Energy Solid State Energy Conversion Alliance (SECA) program. SOFC technology development includes cell performance enhancement, stack building block scale-up, stack tower design and testing, and development of a 250 kW module accommodating multiple stack towers.

Advances in Development of Coal-Based Integrated Gasification Fuel Cell Systems Utilizing Solid Oxide Fuel Cell Technology

FuelCell Energy is developing solid oxide fuel cell (SOFC) systems and technology for very efficient, economically viable, coal-to-electricity power plants utilizing synthesis gas (syngas) from a coal gasifier. In addition to the 500 MW (nominal) size Baseline Power Plant system, a small-scale system (>250 kW) for Proof-of-Concept Module test is being developed. SOFC technology development includes cell performance enhancement, stack building block scale-up, stack tower design and validation tests. Development of a 250 kW module accommodating multiple stack towers is included. The Baseline Power Plant system is designed to remove at least 90% of carbon in the syngas, for sequestration as CO2. The Integrated Gasification Fuel Cell power plant is expected to achieve near-zero emissions to the environment. System optimization to achieve >55% electrical efficiency based on coal higher heating value has been carried out. The SOFC power block layout and factory cost estimate have been generated.
