Modeling and Simulation of a Fuel Cell-based Hybrid Powertrain

This contribution deals with the modeling and simulation of a fuel cell-driven hybrid powertrain. The powertrain consists of several components such as fuel cells, ultracapacitors which are used for storing recuperated energy, DC/DC-converters, and an electric drive motor. The models for the components are presented and discussed and simulations are shown verifying the overall dynamical behavior. The feasibility of changing between different topologies for industrial or vehicular applications as well as easy implementation of power management strategies are the main advantages of these simulation models.
