Thermo-economic modelling and optimisation of fuel cell systems

Abstract

This paper describes and illustrates the application of a methodology for thermo-economic design and optimisation of fuel cell systems. This methodology combines the use of process simulation and process integration techniques to compute thermo-economic performances of fuel cell systems that will be used in a multi-objective optimisation framework. The method allows the generation of integrated fuel cell system configurations and their corresponding optimal operating conditions. It should be used as a preliminary design methodology, allowing the identification of promis ing system configurations, which would be further analysed. The methodology and the thermo-economic models are described and demonstrated for the design of PEMFC hybrid systems, combining fuel cell and gas turbine technologies. © 2005 WILEY-VCH Verlag GmbH & Co.
