SOFC dynamics behaviour simulation model

It is important to acquire the load following performance and change rate of heat of the fuel cell for cogeneration system and system operation as well as control of operation temperature. Because, fuel cell damages by rapid thermal change; its lifetime may be extended by keeping in appropriate temperature. This paper discusses an electrical dynamic behaviour simulation model that considers temperature characteristics, the load following performance, change rate of heat and control of operation temperature. This paper addresses component of the model and typical dynamical results for change of load condition. For example, for power demand change, its output follows within a few ten seconds; its operating temperature can be estimated to increase at a very slow pace as 3 hours. Temperature control methodology installed in a market machine may be estimated by use of the proposed model. The calibration of the model is being conducted using Mitsubishi's site test results.
