When the
literature and the goals of the leading companies in the automotive industry
are examined, it is seen that the transition to electrification and renewable
energy sources in the automotive industry is inevitable. It is known that the
most ideal renewable energy source for mobile systems is hydrogen. The most
efficient conversion of hydrogen into electrical energy occurs with proton
exchange fuel cells. Energy efficiency and environmental pollution factors are
of great importance in transportation. The use of public transportation plays a
major role in improving these factors. In this study, the use of proton
exchange fuel cells on buses used in urban public transportation and the
effects of the bus and its parameters on energy efficiency and hydrogen
consumption were examined. Hydrogen consumption and performance parameters were
examined and evaluated in detail on the created bus model, depending on vehicle
parameters and diffirent driving conditions. Models of the power, linear
vehicle, control and energy systems of the PEM fuel cell bus were created in
the Matlab/Simulink environment. In the power system model, the electric motor
characteristic map is used. Vehicle speed control is provided by PID controls.
In the vehicle linear model, a model of the resistance forces acting on the
vehicle was created. In the energy system, there is a fuel cell system and
battery pack model. The main energy source of the bus energy system is the
hydrogen and fuel cell stack. A battery pack was used to balance the voltage
and meet sudden power needs. Average hydrogen consumption, fuel cell efficiency
and bus range values under different bus parameters and driving conditions were
discussed in detail.
