Fuel cell system
First Claim
1. A fuel cell system, comprising:
- a fuel cell stack for producing electricity, the fuel cell stack comprising an anode outlet outputting an exhaust and a cathode outlet outputting another exhaust; and
a Venturi pump coupled to the fuel cell stack, the Venturi pump comprising;
a main inlet coupled to the fuel cell stack and being supplied with a water or a fuel from the exhaust outputted from the anode outlet of the fuel cell stack;
a secondary inlet coupled to the fuel cell stack and being supplied with a water from the another exhaust outputted from the cathode outlet of the fuel cell stack, the water or the fuel from the exhaust outputted from the anode outlet being mixed with the water from the another exhaust outputted from the cathode outlet in the Venturi pump; and
a main outlet connected to each of the main inlet and the secondary inlet.

Abstract
Provided is a fuel cell system that include at least one fuel cell stack and at least one Venturi pump. The Venturi pump has a main inlet, a main outlet, and a secondary inlet. A main stream flows into the Venturi pump through the main inlet, and is mixed with a secondary stream, which flows into the Venturi pump through the secondary inlet. The fuel cell system of the present invention can include a carbon dioxide separator for separating water or fuel from exhaust outputted from the fuel cell stack, and a mixer for mixing fuel with water. In one embodiment, the Venturi pump can be installed between the carbon dioxide and the mixer. In another embodiment, the Venturi pump can be installed between the fuel cell stack and the carbon dioxide separator. In still another embodiment, the Venturi pump can be installed between the mixer and the fuel cell stack. More than one Venturi pump can be installed in the fuel cell system of the present invention.
