Case Study A: Fuel Cell Power Train for Mopeds
This chapter refers to an experimental study of a 3.5 kW electric power train equipped with a fuel cell system based on a H2/air PEM fuel cell stack of about 2 kW and realized according to the analysis reported in the Chap. 4 . The fuel cell system is characterized in both steady-state and dynamic conditions. The energy losses associated with auxiliary components of the fuel cell system are evaluated, while its dynamic performance is analyzed starting from warm-up operation and investigating different load variation rates, in relation with air supply management issues. Hydrogen purge and membrane humidification strategies are discussed in order to individuate the optimal working conditions for a reliable stack operation. The results of tests on the whole power train during two European driving cycles are finally analyzed, with the aim to evaluate the effect of different control strategies on the power train efficiency.
