Distributed Electrochemistry Modeling Tool for Simulating SOFC Performance and Degradation

摘要

The SOFC is an excellent candidate for stationary and distributed power generation due to the high power density and flexibility to run on coal gas and alternative fuel sources such as landfill gas and pipeline natural gas. To be viable for this application the cost per kW and cell longevity of SOFCs must be further improved. Experimental efforts are ongoing to improve the initial performance and durability of SOFCs through the use of novel materials and microstructural designs. Experimental design and testing of SOFCs is a complex, time consuming process. Computational modeling, which is able to simulate the multi-physics occurring within a SOFC, can be used to inform and guide experimental efforts and help to reduce the amount of experimental testing necessary for new designs and materials. The distributed electrochemistry model, which has been developed under this work, is capable of investigating the electrochemistry and local conditions with the SOFC MEA based on the local microstructure and multi-physics.
