Abstract

A fuel-cell system, in particular for a vehicle, has a device for supplying the operating agents for a fuel cell and an electrical energy accumulator. The energy accumulator is composed of a battery and of an intermediate charge store which has a lower internal resistance than the battery. A switch is provided in the electrical connection between the energy accumulator and the fuel cell.
