Abstract

The invention relates to a fuel cell system comprising a fuel cell (2) connected to electrical connection lines (3, 4). The fuel cell (2) can be short-circuited in the event of an emergency cut-out being required.

Description

technical field [0001] The invention relates to a fuel cell system having at least one fuel cell, which is connected to electrical connecting lines. Background technique [0002] When using a battery as an energy source in a vehicle, it is known to disconnect or separate the system from the power source, ie the battery, at both poles by opening an electromechanical switch. Control devices for such batteries usually include two contactors, which separate the battery from the contacts leading to the outside. Such an embodiment is also implemented in a corresponding manner in fuel cell systems today. A disadvantage of this embodiment is that the components are more complex / expensive, since the actuating means must be realized at least in a double manner in order to meet safety standards. Another disadvantage of this embodiment is that high voltages can still occur after the separation, which can endanger the safety of personnel. A disadvantage of this known embodiment with c...
