Abstract: A fuel cell system (100) having a fuel cell stack (10) and a fuel cell cooling system (40) to cool the fuel cell stack (10), including a coolant path (4) into which the fuel cell stack (10) is integrated so as to transfer heat and in which at least one cooler (43) or heat exchanger is arranged. It is provided that the at least one cooler (43) or heat exchanger that does not have shock-hazard protection is interconnected so as to establish equipotential bonding (47), whereby at least one control element is arranged in the connection of the at least one cooler (43) or heat exchanger to equipotential bonding (47). Moreover, a vehicle having such a fuel cell system (100) is disclosed.
