On the optimum powertrain configuration of fuel cell powered vehicle for minimum hydrogen consumption

In the study, we investigated the hybrid systems to reduce the hydrogen consumption of fuel cell systems. We used super capacitors as auxiliary power source for hybridization. We set four different configurations using super capacitors and DC/DC converters. We performed the tests on İstanbul University hydrogen powered vehicle. We extracted the energy and hydrogen consumptions of fuel cell for each configuration and determined optimum configuration.
