Abstract
Official abstract text for this publication.
Various hot box fuel cell system components are provided, such as heat exchangers, steam generator and other components.
First claim
Opening claim text (preview).
The invention claimed is: 1. A fuel cell system comprising: at least one fuel cell stack or column; and a cathode recuperator heat exchanger comprising an inner heat shield, an outer heat shield, a separator formed between the inner and outer heat shields, an air exhaust conduit located between the separator and the outer heat shield, and an air inlet conduit located between the separator and the inner heat shield, wherein an air inlet stream in the air inlet conduit flowing to the at least one fuel cell stack or column is heated by an air exhaust stream in the air exhaust conduit flowing from the at least one-fuel cell stack or column; wherein the air inlet conduit outlet of the cathode recuperator heat exchanger faces a middle portion of the at least one fuel cell stack or column, such that the air inlet stream exiting the air inlet conduit of the cathode recuperator flows directly towards a middle portion of the at least one-fuel cell stack or column, before flowing towards end portions of the at least one fuel cell stack or column, the end portions being disposed at opposing ends of the at least one fuel cell stack or column, in a stacking direction of the at least one fuel cell stack or column, wherein the length of each end portion extends only 10-25% of the length of the at least one fuel cell stack or column, the middle portion is disposed between the end portions in the stacking direction, and the length of the middle portion is 50-80% of the length of the at least one fuel cell stack or column. 2. The fuel cell system of claim 1 , wherein the air inlet conduit outlet comprises a circular opening that faces the middle portion of the at least one fuel cell stack or column. 3. The fuel cell system of claim 1 , wherein the separator comprises a corrugated fin plate or sheet.
