Molten carbonate fuel cell technology improvement
The overall objective of this program is to define a competitive CG/MCFC power plant and the associated technology development requirements and to develop an improved cell configuration for molten carbonate fuel cells which has improved performance, has reduced cell creep and electrolyte management consistent with 40,000 hour projected life, reduces existing cell cost, and is adaptable to a range of power plant applications. Component design specifications for the end-cells of the alternative cell configuration were completed. Testing to evaluate new components was performed on 14 cells during this reporting period with eight tests started and terminated, and six tests continuing into the next reporting period. A test and performance summary of all the single cell tests conducted to date on this program is presented in Table 1. A single cell test to qualify new matrix materials and matrix reinforcement was successfully completed. Integrated cell testing of new anode- and cathode-side components was completed. Single cell tests were conducted to identify the electrolyte fill procedure for the new cell configuration. Methods of fabricating manifold seals from the new candidate materials are being developed. Preparation of construction drawings for the 1-ft{sup 2} short stack was continued. Fabrication of repeating cell components for the 1-ft{sup 2} short stack was initiated. Trials to tape cast electrodes and matrices were initiated, tooling to form current collectors is being fabricated, and existing tooling to form separator plates is being modified. Non-repeat components from the previous 1-ft{sup 2} short stack that are acceptable for re-use were identified. New non-repeat components that are required have been ordered. Preparation of the test stand for the 1-ft{sup 2} short stack test was initiated. 2 figs., 3 tabs.
