Fuel cell system's air supply controlling system for motor vehicle, has control unit receiving signals corresponding to temperature, pressure and air flow, and calculation unit calculating air flow envisaged for determining air flow

摘要

The device has a controlled unit constituted by a compressor (3) and an electric motor (4) for compression of air, and a control valve (6) for regulation air flow and mounted between a compression unit and a fuel cell. An electronic control unit (26) receives signals corresponding to temperatures, pressures and air flow admitted in the fuel cell and emitting control signals for the compression unit and the controlled valve. A calculation unit calculates the air flow envisaged for determining the air flow admitted in to the fuel cell. An independent claim is also included for a method for controlling the air supply of a fuel cell system in a motor vehicle.
