摘要
A fuel cell system (10) for a motor vehicle is proposed, the fuel cell system (10) comprising a fuel cell (30) and an air supply system for supplying air to the fuel cell (30), in particular a fuel cell stack of the fuel cell (30), and for removing Air from the fuel cell (30), the air supply system comprising a supply air duct (40) for supplying air to the fuel cell (30), an exhaust air duct (45) for discharging moist air from the fuel cell (30), a cooling device (50) for cooling air compressed by a compressor (84) in the supply air duct (40), and a protective device (20) for protecting the fuel cell (30) from air at a temperature above a predetermined first temperature limit, which is generated by the compressor (84) the fuel cell (30) flows, the protection device (20) in and / or on the supply air duct (40) between the cooling device (50) and d er fuel cell (30) is arranged, and wherein the protective device (20) releases a connection (25) between the supply air duct (40) and the exhaust air duct (45) bypassing the fuel cell (30) when the temperature of the air at the protective device ( 20) exceeds the predetermined first temperature limit.
