Abstract
A fuel cell system includes at least one electrochemical pump separator to separate hydrogen and carbon dioxide from a fuel exhaust stream.
Claims14
A fuel cell system comprising:
- a hotbox;
- a fuel cell stack disposed in the hotbox;
- a fuel exhaust conduit that receives fuel exhaust output by the fuel cell stack;
- a fuel exhaust separator that separates liquid from the fuel exhaust;
- and
- a recycling conduit that fluidly connects the fuel exhaust to the fuel inlet conduit.
3 more elements
A method of operating a fuel cell system comprising:
- receiving, at a fuel exhaust conduit, fuel exhaust output by a fuel cell stack disposed in a hotbox;
- separating, at a fuel exhaust separator, liquid from the fuel exhaust;
- and
- fluidly connecting, at a recycling conduit, the fuel exhaust and the fuel inlet conduit.
1 more element
A fuel cell system comprising:
- a hotbox;
- a fuel cell stack disposed in the hotbox;
- a fuel exhaust conduit that receives fuel exhaust output by the fuel cell stack;
- a fuel exhaust splitter that fluidly separates fuel exhaust to a recycling conduit and a processing conduit;
- wherein the recycling conduit fluidly connects the fuel exhaust to the fuel inlet conduit, and the processing conduit is fluidly connected to a gas separator.
2 more elements
A fuel cell system, comprising:
- a fuel cell stack;
- an anode recuperator heat exchanger;
- an anode exhaust cooler heat exchanger;
- a splitter located between the anode recuperator heat exchanger and the anode exhaust cooler heat exchanger;
- at least one electrochemical hydrogen pump separator;
- and
- anode exhaust cooler bypass fluidly connecting the splitter to the least one hydrogen pump.
