Method for detecting compressor surge in a fuel cell system using a mass flow meter |
摘要 |
A method for detecting compressor surge in a fuel cell system. The system includes a turbomachine compressor that delivers charge air to the cathode side of a fuel cell module. A bi-directional mass flow meter measures the airflow through the compressor, and provides an indication of a reverse airflow through the compressor for surge protection. A controller receives a signal from the mass flow meter indicative of the reverse flow. The controller controls a motor driving the compressor and a back pressure valve at the cathode exhaust of the fuel cell module to control the pressure in the fuel cell module to remove the surge condition.
