A high temperature electrochemical converter provides regenerative heating of electrochemical converter reactants to an operating temperature using an exhaust flow. Additionally, a radiant thermal integration configuration transfers heat from an electrochemical converter assembly to power a bottoming plant, thereby achieving flexible and efficient system design. In a fuel cell operating mode, for example, it facilitates the recovery of waste heat of the fuel cell reaction for integration with bottoming thermodynamic devices, such as a gas or steam turbine. The radiant thermal integration is accomplished by efficient radiative heat transfer between the external columnar surface of the converter assembly and the heat transfer assembly containing the working medium of a heat sink or a heat source device, and by a regenerative process where incoming reactants are heated to the converter operating temperature by outgoing exhaust. |
