Samenvatting

Fuel cell hybrid power trains comprise an energy storage to supply peaks in the power demand and to
facilitate regenerative braking. In terms of control systems, the presence of storage provides additional
freedom to minimize the vehicle’s fuel consumption. In a previous paper [1] an analytical solution to
the energy management problem for fuel cell hybrid propulsion systems was derived and compared with
existing strategies like the Equivalent Consumption Minimization Strategy (ECMS) [1–4]. An experimental
study has been carried out on a Fiat Doblo, which was converted from a regular gasoline powered
vehicle into a fuel cell hybrid vehicle. The fuel cell drive train comprises a 10kW proton exchange membrane
fuel cell stack connected by means of a DC/DC converter to a Li-ion battery. The aforementioned
analytical energy management strategy was used during the experiments. The experiments were carried
out on a roller test bench and on the road. The experiments were conducted not only to validate the energy
management strategy and the underlying models but also to establish its practical value. The paper
shortly reviews the energy management problem and solution. Next the vehicle and its fuel cell hybrid
drive train are presented as well as the experimental setup. The paper finishes by stating the experimental
results and the conclusions.
