โœฆ Synopsis

A review of an energy and exergy analysis of the KTI 25 kW fuel cell system is described. This system consists of a fuel cell and a fuel processor. An examination of the system's integration concept is done with the aim of pinpointing the existing losses. The exergy calculations are performed with the Aspen Plus programme using a Fortran extension. Energy and exergy calculations are presented in a Sankey and Grassmann diagram, respectively. The system's major energy losses are involved with off-gases, while the system's major exergy losses are associated with internal process irreversibilities. It is concluded that the exergy calculations pinpoint the losses accurately and that the exergy analysis gives a better insight of the system's process.
