Abstract

This paper describes the architecture and key equations of FCSys, a library to model proton exchange membrane fuel cells (PEMFCs) in Modelica. The motivating goal of this work is to reconcile many of the published models of PEMFCs and combine them in a reconfigurable PEMFC model that is effective for a variety of uses. It is necessary to distill equations from fuel cell literature into forms that at once capture the essence of the physical interactions, are conducive to the physical modularity of the device, and work within the constraints and take full advantage of the Modelica language. Since the behavior of PEMFCs depends on both advection and diffusion, a suitable alternative to the Modelica Fluid library and the stream concept is necessary. The proposed solution uses a
