Especially, because of its convenient integration with micro gas turbines for future stationary, high-efficiency, clean electric power generation system, there is an increasing need to develop high-pressure (pressurized-assembly) planar SOFC technology in many advanced developed countries. Just like the gas turbine technology, the high-pressure SOFC technology is also recognized as a country power symbol. This is the motivation of the present proposal. Thus, this proposal focuses on experimental tests and measurements along with numerical simulations and analyses, including three main objectives: (1) To establish an innovative high-pressure SOFC testing platform, and thus a series of high-pressure (1~5 atm) experiments can be performed to understand the high-pressure impact on the cell performance of SOFC stacks; (2) to establish 3D high-pressure electrochemical reaction flow numerical models, and thus predictions of the cell performance of SOFC stacks under high-pressure conditions can be obtained and compared with experimental data; (3) to establish the high-pressure standard cell test procedure and combine these aforementioned experimental and numerical results to evaluate possible difficulties and problems encountered when integrating the high-pressure planar SOFC with micro gas turbine power generation systems. This three-year proposal aims to establish the real testing platform for high-pressure planar SOFC performance measurements. The schematic setup is presented in the figure as shown on the previous page. First year working items: To establish an innovative pressurized-assembly SOFC testing platform and conduct a series of high-pressure (1~5 atm) experiments so that the impact of high pressure conditions on the cell performance of single-cell stacks can be measured. Also, the standard cell testing procedure under high pressure conditions will be established. Second year: Continuing to perform the first year work, we will establish several 3D high-pressure electrochemical reaction flow numerical models, so that predictions of the cell performance of SOFC stacks under high-pressure conditions can be obtained and compared with experimental data. Third year: 第三年度:Keeping the second year work going, we will investigate micro ion transport phenomena in single-cell stack under high pressure conditions. Finally, using these aforementioned experimental and numerical results, we will evaluate possible difficulties and problems encountered when integrating the high-pressure planar SOFC with micro gas turbine power generation systems. The self-evaluation of the present proposal is given. We believe that this proposal is of importance in academic values and has great potential for future industrial application. It is also a challenging research. The principle investigator (PI) has recently successfully established an atmospheric high-temperature SOFC testing platform for testing large-area full cells including flow distributors. The PI’s laboratory has established the standard test procedure for single-cell stacks under normal pressure conditions and thus accumulated the system integration experience for SOFC. Some achievements in terms of publications are listed below. 1. C. M. Huang, S. S. Shy and C. H.

Furthermore, the statistical methods for analyzing the measured data are also available. Thus, the possibility of completing this proposal should be very high. The PI and his post-doc and graduate students will all do their best to continuously produce important results with the highest quality in the international SOFC society. 研究期間:10008 ~ 10107
