With the emergence of hydrogen as an important energy transport medium, fuel cells have become a
technology of hot interest in electrified industries, including power generation, automotive and
transportation, and aerospace propulsion. The use of fuel cells in fact is an intermediate between
traditional power trains and battery-electric applications in automotive and aerospace because the
hydrogen fuel can be quickly filled, is light compared to batteries, and the resulting fuel cell system
power density is much closer to the incumbent power train technologies than fully battery technologies.
However, fuel cell systems rely on turbomachinery as a core component in both providing required
flow streams as well as extracting the full energy potential from the system.
While many practitioners of turbomachinery have strong background in applying turbomachinery
design and analysis to incumbent traditional power systems, the relatively newer fuel cell technologies
often have very different operating regimes that engineers and operators should know to effectively
design and operate such systems. This tutorial is aimed specifically to introduce the unique aspects of
fuel cell technologies that enable both theoretical researchers and practitioners of these systems to
maximally utilize their design experience.
The fuel cell is demystified by starting at the very fundamentals of fuel cell electrochemistry,
proceeding to thermodynamic characterization and modelling of fuel cell systems, and discussing how
system architectures can be optimally designed for such systems. Simple modelling techniques will be
shown that enable practitioners to model and predict the performance of a system at design and off design operating conditions. Elements of turbomachinery design as it applies to fuel cell systems will
also be briefly covered. Finally, the specific application of fuel cell system modelling in automatic,
aerospace, and power generation will be discussed, with some case studies of existing system designs
presented.
