The overall process is described first followed by engine fuel cell integration concepts design assumptions a description of the major equipment input data a heat and material balance and then the modeling approach and methodology. Process Description This design utilizes a unique combination of fuel cell turbine and recuperator to achieve a highly efficient cycle in a small compact market-driven size. The flow and heat requirements of components in the micro-turbine and Solid Oxide Fuel Cell Company SOFCo CpnTM Co-planar n-stack fuel cell module have been matched resulting in a highly integrated package. The micro-turbine is a 70 kW gas turbine engine under development by Northern Research and Engineering Corporation NREC . The SOFCo CpnTM concept evolved from recognizing the impact of the balance of plant BOP on the economy and efficiency of the total fuel cell system. The design optimizes the total fuel cell system and maximizes the efficiency of the system while simultaneously reducing the number of high temperature components peripheral to the stack. The CpnTM module shown in Figure 1 consists of a multi-stack arrangement that enhances efficiency through effective thermal coupling of the stacks and the fuel processors. The CpnTM power system is comprised of planar PSOFC stacks fuel processor components and the BOP equipment. The most significant feature of the CpnTM is the Thermally Integrated PSOFC Module that houses the fuel cell stacks reformer catalyst tubes and a spent fuel burner.
