DEVELOPMENT OF A SOLID-OXIDE FUEL CELL / GAS TURBINE HYBRID SYSTEM
MODEL FOR AEROSPACE APPLICATIONS
ABSTRACT
Recent interest in fuel cell-gas turbine hybrid applications
for the aerospace industry has led to the need for accurate
computer simulation models to aid in system design and
performance evaluation.
To meet this requirement, solid oxide
fuel cell (SOFC) and fuel processor models have been
developed and incorporated into the Numerical Propulsion
Systems Simulation (NPSS) software package.
The SOFC and
reformer models solve systems of equations governing steadystate performance using common theoretical and semiempirical terms.
An example hybrid configuration is presented
that demonstrates the new capability as well as the interaction
with pre-existing gas turbine and heat exchanger models.
Finally, a comparison of calculated SOFC performance with
