As a result of its many capability advantages, together with excessive electric potency and occasional environmental emissions, stable oxide gas mobilephone (SOFC) know-how is the topic of intensive learn and improvement efforts by means of nationwide laboratories, universities, and personal industries. In those complaints, foreign scientists and engineers current fresh technical growth on materials-related features of gasoline cells together with SOFC part fabrics, fabrics processing, and cell/stack layout, functionality, and balance. rising developments in electrochemical fabrics, electrodics, interface engineering, long term chemical interactions, and extra are included.This ebook is compiled of papers awarded on the complaints of the thirtieth overseas convention on complicated Ceramics and Composites, January 22-27, 2006, Cocoa seashore, Florida. geared up and backed by way of the yank Ceramic Society and the yank Ceramic Society's Engineering Ceramics department along side the Nuclear and Environmental know-how department.

53 Performance Degradation of SOFC Using Chromium-Containing Alloy Interconnects CONCLUSIONS A test consisting of an anode-support fuel cell using chromium-bearing interconnect material was tested for a long (>5000 hour) duration. During this time, the performance of the cell was measured while the cathode air flow was humidified with 3% water vapor. This results in an immediate, recoverable loss in performance most likely due to increase concentration polarization or water adsorption. A longer duration effect is non-recoverable and leads to permanent cell degradation.

This figure shows the final 2000 hours of the test in ternis of stack potential at a current density of 250 mAacm-’. The atmosphere was humidified four time during this period: once at 3350 hours for a brieftime and again at 3400,3600, and 3900 hours, each for a duration of 168 hours. During each of these times, there was an immediate decrease in cell perfomiance during the introduction of water vapor of about 10 mV. which was recoverablr upon returning to dry conditions. 14 mV,h”, a decrease which was not recoverable upon returning to dry conditions.

It was found that no decrease in terminal voltage occurred during the initial 2,000 hrs. 000 hrs. (1 2iKi0 411011 hlt(ll1 XOO~ il11llK) 12000 Time (11) Figure 5.
