Abstract
A system for adding sulfur to a reformate stream feeding a fuel cell stack, having a sulfur source for providing sulfur to the reformate stream and a metering device in fluid connection with the sulfur source and the reformate stream. The metering device injects sulfur from the sulfur source to the reformate stream at a predetermined rate, thereby providing a conditioned reformate stream to the fuel cell stack. The system provides a conditioned reformate stream having a predetermined sulfur concentration that gives an acceptable balance of minimal drop in initial power with the desired maximum stability of operation over prolonged periods for the fuel cell stack.
Claims7
A system for adding sulfur to a reformate stream feeding a fuel cell stack having Ni—YSZ anodes, comprising:
- a sulfur source for providing sulfur to said reformate stream;
- and
- a metering device in fluid connection with said sulfur source and said reformate stream, wherein said metering device injects sulfur from said sulfur source to said reformate stream at a predetermined rate, thereby providing a conditioned reformate stream to said Ni—YSZ anodes of fuel cell stack.
