Summary:This chapter provides the necessary tools to describe the basic operation of a fuel cell together to build a complete fuel cell model. The fuel cell model includes thermodynamics, reaction kinetics, charge transport, and mass transport. After discussing the big picture in the context of a simple fuel cell model, the author will delve into the details of several more sophisticated modeling approaches. One example is a flux balance‐based approach, which one use to model both a PEMFC and an SOFC. Still more complex is the computational fluid dynamics (CFD) approach to fuel cell modeling. CFD dynamics modeling allows the detailed interactions between flow structure geometry, fluid dynamics, multiphase flow, and electrochemical reaction to be simulated numerically. These more sophisticated modeling techniques can provide predictive capability and may one day allow fuel cell designers to better optimize fuel cells computationally before ever testing them in the laboratory.
