Work proceeded this quarter mainly under three program tasks. Under Task 1.0, the four candidate power plant configurations were ranked and the Steam Injection System was recommended as the reference plant design. The Steam Injection System was chosen based on its overall simplicity, high performance level, balance of plant state-of-technology readiness and economic attractiveness. Work was initiated on refinement of fuel cell piping costs. Under Task 2.0, work continued on cell component (anode, cathode, current collector and electrolyte) development and stack design and analysis. Corrosion test results after 1000 hours in fuel gas and 3000 hours in cathode gas are reported for 310SS, 316SS, 446SS, chromium, IN690, and GE2541. In the cathode environment, 310SS and GE2541 show good thermal cycling properties, whereas the other alloys show scale spalling during thermal cycling. Examination of a Ni-clad 316SS anode current collector tested in a cell for 2000 hours shows second phase precipitates along the grain boundaries of the nickel. Experiments with different grades of nickel in an anode atmosphere were started in order to evaluate the effects of impurities present in the metals. Under Task 4.0, work continued on installation of the bench scale single cell test facilities, one atmospheric and one pressurized (up to 10 atm), which will be used in cell testing with contaminants in the fuel and oxidant.
