Abstract-In a passive hybrid topology, the fuel cell is directly
electrically coupled to the battery. Although no DC/DC
converters are used, it is possible to control the fuel cell power
by adjusting its operating pressure, and thus the power sharing
between the fuel cell and the battery becomes actively
controlled. Using this concept, simulations results show that the
power demand of an electric vehicle is fulfilled while sustaining
the battery state of charge. By removing the DC/DC converter,
the hybrid system becomes simpler, lighter and cheaper.
