Abstract

A fuel cell vehicle comprises an electric drive system and a fuel cell system for providing electric energy for the drive system. According to the invention, the electric drive system is set up for regenerating braking energy, and devices are provided for the direct utilization of the regenerated braking energy in at least one energy-consuming component of the fuel cell system. This direct braking energy utilization in the fuel cell system increases the degree of energy utilization without the requirement of a separate intermediate energy storage device for the intermediate storing of regenerated braking energy.
