Abstract

The invention relates to a method and apparatus for controlling and for setting the switching states of switches which are connected to the electrical poles or outputs of a fuel cell and which are followed by a network, which is fed from the fuel cell, and has loads. The invention is preferably suitable for use in a vehicle. The switches are opened if the fuel cell and/or the vehicle assume critical states.
