Abstract
Pressure differential 6 between cathode 2 and anode 3 is controlled by valve 24, 26 of valve complex 20. The complex 20 is located within anode recirculation loop 8, 9, 3, 20 whereby controllability is not lost with no flow through the anode. Control is thereby retained during nitrogen purging of the cathode. An orifice 22 in the valve complex 20 precludes accidental full closure of the complex, and is selected to avoid immediate damage to the fuel cell on such closure.
