Abstract

A multi-stream heat exchanger includes at least one air preheater section, at least one cathode recuperator section, and at least one anode recuperator section, wherein each section is a plate type heat exchanger having two major surfaces and a plurality of edge surfaces, a plurality of risers through at least some of the plates, and a plurality of flow paths located between plates. The cathode recuperator section is located adjacent to a first edge surface of the anode recuperator, and the air preheater section is located adjacent to a second edge surface of the anode recuperator section.

First claim

What is claimed is:

1. A fuel cell system, comprising:
a fuel cell stack;
a fuel inlet conduit configured to provide a fuel inlet stream into the fuel cell system;
an air inlet conduit configured to provide an air inlet stream into the fuel cell system;
an anode tail gas oxidizer;
a cathode exhaust conduit configured to provide a cathode exhaust stream from the fuel cell stack into the anode tail gas oxidizer;
an anode recuperator heat exchanger;
an anode exhaust condu…
