The high temperature molten carbonate fuel cell (MCFC) operating on natural gas fuel offers an exceptional opportunity for providing economically competitive, high efficiency, low emissions power generators for utilities and industrial and commercial cogenerators. The primary goal of the project was to establish a path to develop competitive natural gas fueled MCFC products. A coal fueled MCFC system study funded by DOE under contract DE-AC21-MC23270 was used as a basis to define natural gas fuel products with a high degree of commonality with the coal gas system. In this way, the natural gas systems could be derived from the DOE coal-fueled system with a minimum of non-recurring cost. Key results of the effort are as follows: A minimum non-recurring cost approach to developing natural gas systems from the DOE coal gas/natural gas systems was defined based on a dual fuel capable system which could be developed for both natural gas and coal gas fueled applications; Attractive natural gas products were identified in the 3 MW to 22 MW scale with heat rates as low as 6000 Btu/kWh (HHV); A preliminary definition of a 300 kW proof-of-concept test, called an Integrated System Test (IST), was completed; Critical natural gas specific issues were identified as: (1) anode and cathode recycle blowers; (2) sensible heat reformer (SHR); and (3) catalytic burner; Subscale testing of sensible heat reformer and catalytic burner catalysts was completed to establish a design data base for these critical components.
