【 摘 要 】

This report summarizes the progress made in development of Direct FuelCell/Turbine{reg_sign} (DFC/T{reg_sign}) power plants for generation of clean power at very high efficiencies. The DFC/T power system is based on an indirectly heated gas turbine to supplement fuel cell generated power. The DFC/T power generation concept extends the high efficiency of the fuel cell by utilizing the fuel cell's byproduct heat in a Brayton cycle. Features of the DFC/T system include: electrical efficiencies of up to 75% on natural gas, 60% on coal gas, minimal emissions, simplicity in design, direct reforming internal to the fuel cell, reduced carbon dioxide release to the environment, and potential cost competitiveness with existing combined cycle power plants. Detailed design of the packaged sub-MW alpha DFC/T unit has been completed for mechanical and piping layouts and for structural drawings. Procurement activities continued with delivery of major equipment items. Fabrication of the packaged sub-MW alpha DFC/T unit has been initiated. Details of the process control philosophy were defined and control software programming was initiated.
