Information on energy demand and traversal times along segments of a route is used to operate a fuel cell of an automotive drive in order to minimise fuel consumption. The buffering capacity of a battery is exploited to proactively leave the fuel cell idle or run it as close as possible to its maximum efficiency power level. Additionally, recuperation energy is buffered. Shortest paths in so-called power graphs correspond to approximately optimal fuel cell operation along a given route. In principle, minimum consumption routes can be computed in the same way. The approach targets planning rather than control.
