Modelling and simulation of the fuel cell power module of the HYDRO-GEN car.

A fuel cell power module is a complex system in which interactions between different components are chemical, hydraulic, thermal, mechanical and elect rical. Design and optimization of such a system cannot be limited to a sepa rate study of each element, but needs a complete system analysis using mode lling and simulation. The bondgraph theory is specially adapted to the mult iple phenomena involved. The paper presents the modelling methodology used for the power module of the project HYDRO-GEN, illustrating it with some ty pical examples and presenting the first qualitative simulations results.
