The automotive industry is facing the challenge to realize the turn over to a climate-neutral mobility. The use of fuel cell powertrains are a promising way. Especially the short duration for the refueling of the tank in combination with an acceptable range and the separation of energy production and the refueling process show the advantages of the powertrain technology against the battery electric vehicle for the customer. Current vehicle concepts use PEM based fuel cells, which provide in combination with low battery capacities the power for the electric motor. The efficiency of the entire powertrain is influenced on the one side by the design of the fuel cell and the battery size and on the other side by the dynamic power split.
The actual series standard of powertrain topologies are fuel cell vehicles with a big fuel cell system and a small battery size. These powertrains shows advantages regarding maximum speed, efficiency and performance. Due to their size these powertrains show big challenges in terms of complexity, costs and long life durability. IAV used their 0D/1D simulation framework to layout a fuel cell based hybrid powertrain (fuel cell system and battery) with a very long range and high durability for the use in a medium-size passenger car. Beside the long range also very low costs can be achieved by the use of a small stack, less components and a low effort for the calibration of the fuel cell system. This powertrain is simulated by different cycles to show the performance in terms of different target values. Furthermore the innovative fuel cell system powertrain is compared with a battery electric vehicle in terms of long range capability. This publication closes with a cost analysis of the fuel cell based powertrain for the automotive market in 2025.
