Obiettivo Objectives The objective of the proposed work is to develop 50 kW SOFC technology based on the multiple cell array concept of Siemens with a metal separator plate. The existing technology has to be upscaled to bigger stacks delivering a power output of 12.5 kW. At the same time the behaviour of cells and stacks using methane as fuel gas has to be tested and improved. The knowledge gained will be implemented in a test plant with pre-reforming. The project aims at durable, low cost stack technology for simple SOFC systems for CHP applications and electricity production in combined cycles. Technical Approach To reach the objectives the multiple array concept of Siemens has to be upscaled for the 12.5 kW stacks, taking into account the use of CH4, i.e. pre-reforming or recycling of the gas and internal reforming in the fuel cell stack. For testing the 50 kW module a test plant will be designed and constructed. For this test plant a pre-reformer unit will be developed and the power conditioning will be investigated. In order to reach the final goal of the project, the 50 kW demonstration, two different options are available which will be explored, i.e. line using H2 as the fuel gas with O2 or air as the oxidant and a line with CH4 as the fuel gas. At least a 3 kW experiment with CH4 will be performed in the second year. The successful performance of this test is a prerequisite for the operation of the 50 kW test with methane. In parallel to the stack development, the electrodes will be further optimized and tested, especially concerning the behaviour with internal reforming. This will lead to suitable cells for internal reforming and the necessary pre-reforming rate will be elaborated. Catalysts available for the pre-reformer will be investigated. In collaboration with the manufacturer of the bipolar plate material, the parts for the different stacks will be made, as well as sealing, functional layers, catalysts and cells. All results gained in the different work groups will be implemented in optimized cells, which will be tested over 5000 hours to show the long term stability. Expected Achievements and Exploitation SOFC power plants have a great potential compared to conventional systems concerning electrical efficiency and environmental pollution. The specific emissions are reduced by one or two orders of magnitude. In the lower power range electrical efficiencies above 50 % can be reached. Above 10 MW the waste heat can be used in gas and steam turbines. By this measure, efficiencies up to 70 % can be realized. Besides this, an excellent part load behaviour of the SOFC system can be expected. A successful demonstration of SOFC systems will lead to an introduction on the market; somewhere between 2005 and 2010, starting with small capacity units (i.e. < 10 MW) for distributed power and cogeneration application.
