Abstract
A device for controlling the differential pressure between an anode area and a cathode area of a fuel cell has a differential pressure sensor for measuring the differential pressure between the anode area and the cathode area. A first actuator controls the flow of fuel into the anode area, and a control device regulates or controls the first actuator, on the basis of the signal of the differential pressure sensor.
Claims14
A device for controlling differential pressure between an anode area and a cathode area of a fuel cell, wherein:
- the device is connectable with a refuellable storage tank for hydrogen and has a first actuator for adjusting pressure in at least one of the anode area and the cathode area;
- a differential pressure sensor is provided for measuring the differential pressure between the anode area and the cathode area;
- and
- a control device controls the first actuator on the basis of a differential pressure signal of the differential pressure sensor.
A method of controlling differential pressure between an anode area and a cathode area of a fuel cell which is supplied with hydrogen from a refuellable storage tank, said method comprising:
- measuring differential pressure between the anode area and the cathode area by means of a differential pressure sensor;
- and
- adjusting pressure in at least one of the anode area and the cathode area based on measured differential pressure.
