In this chapter, we explore model predictive control of fuel cell electric vehicles (FCEVs), a type of vehicle that utilizes the chemical energy of hydrogen to generate electricity for their power train. Since vehicles are typically utilized for mobility purposes only for a fraction of the time, the energy stored in the onboard hydrogen tanks of these vehicles also can be used to supply power when they are parked. Our focus is on examining how to control the operation of FCEVs, ensuring the fulfilment of constraints imposed by both electrical and transportation networks while minimizing operational costs.
