Passive anode gas recovery system for fuel cell
A passive anode gas recovery system for fuel cells is revealed. The system includes a fuel cell, a fuel supply device, an electronically controlled regulator, a first ejection module, a second ejection module, a hydrogen recovery module, and a controller. The system is a passive fuel recovery system disposed on an outlet end of an anode of the fuel cell. By the controller, the hydrogen recovery module recovers unconsumed hydrogen gas in the fuel cell provided by the fuel supply device into two ejection modules with different orifice diameters for recycling and reuse. The system has advantages of low cost, no extra energy consumed, and no external controller required. The system can be applied to developing fuel cell systems with high efficiency and low cost.
