FUEL CELL CONTROL SYSTEM AND FUEL CELL CONTROL METHOD

The present invention relates to the field of fuel cells, and in particular, to a fuel cell control system and a fuel cell control method. The fuel cell control system comprises: a reactor (20); an air compressor (10) having a compression chamber (101), the compression chamber (101) having an air inlet (113) and an air outlet (114), a rotatable pressure wheel (300) being provided in the compression chamber (101), and the air outlet (114) being communicated with the reactor (20); a control flow channel, a first end of which is communicated with an air inlet side of the pressure wheel (300), and a second end of which is communicated with a wheel back side of the pressure wheel (300), a reflux valve (15) used for regulating the flow of the control flow channel being provided on the control flow channel; and a central control unit (30) communicationally connected to the reflux valve (15) to control the opening of the reflux valve (15).
