Airflow control in fuel cell for vehicles based on stack allowable current
In order to avoid "oxygen hungry" in fuel cells under the loading condition and improve response speed of fuel cells for vehicles, an fuel cells air-flow control method containing allowable current in stack was proposed. Firstly, based on the actual air flow in the stack cathode, the allow...

| description | In order to avoid "oxygen hungry" in fuel cells under the loading condition and improve response speed of fuel cells for vehicles, an fuel cells air-flow control method containing allowable current in stack was proposed. Firstly, based on the actual air flow in the stack cathode, the allowable current of the stack was estimated to limit the stack current. Then, the demand current was obtained according to the load demand power. Finally, the required air flow was dynamically obtained to control the speed of the compressor. Meanwhile, a compensator was designed to keep the reference current with the stack current. The results show that when the load current demand power is rapidly increased, the control method with the stack allowable current has a short load time and can avoid "oxygen starvation". |
