Overview

The Open-Source PEMFC Simulation Tool (Opem) is an open-source mathematical simulation package for polymer electrolyte fuel cells. It contains a database of physical phenomena equations, and kinetics mathematical models in order to perform static/dynamic analysis of PEMFC. The goal of the software is to prepare a platform for collaborative development of PEMFC mathematical models.
