<p><P>PROBLEM TO BE SOLVED: To specifically provide a high temperature heat exchanger structure for a fuel cell. <P>SOLUTION: The invention relates to the heat exchanger 110 for a hot fuel cell 101. The heat exchanger has a first flow circuit 111 for receiving a cool air stream and a second flow circuit 112 for receiving a hot fluid 114 coming from the fuel cell and the first and second flow circuits have common surfaces for heat exchange. In accordance with the invention, each of the first and second flow circuits 110, 112 has a plurality of concentric annular ducts 1110-1115; 1120-1123 that are interconnected. Two walls of each duct are mechanically decoupled from each other so that the two walls can expand independently from each other and are evaded from mechanical stresses within the heat exchanger. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
