AIR MANAGEMENT SYSTEM AND A METHOD FOR CONTROLLING INTAKE AIR PRESSURE AND EXHAUST BACK PRESSURE OF A FUEL CELL SYSTEM

The present disclosure relates to an air management system and a method for controlling an intake air pressure and an exhaust back pressure of a fuel cell system. It further relates to an arrangement comprising a fuel cell system and such an air management system, and to a vehicle. The air management system includes an air pressurizing device arranged to feed intake air to an air compressor of the fuel cell system, a pressure regulating device arranged for regulating the exhaust back pressure, a pressure detection device for detecting an ambient air pressure, and a control device configured to control the air pressurizing device and the valve in dependence on the detected ambient air pressure, wherein the control device is configured to control the intake air pressure to a predetermined first pressure level, and to control the exhaust back pressure to a predetermined second pressure level.
