TI  - SOFC development in Jülich / Utilization of Bio-Syngas in Solid Oxide Fuel Cell Stacks

AB  - The main focus of SOC development at Forschungszentrum Jülich is on optimized, mass-production compatible manufacturing technologies of anode-supported fuel cells (ASCs) and on understanding the degradation phenomena of fuel cells during long-term stack operation. Primary achievements include the continuous operation of a planar SOFC stack for > 93.000 hours as well as new insights into the mechanisms of chromium-related cathode degradation. The coupling of a biomass gasifier with an SOFC stack has been demonstrated within a joint project with TU Munich, and the degradation effects on cell and stack level have been investigated with tar-containing model gases as well real bio-syngas. The drastic degradation effects observed demonstrate that substantial improvements of the coking resistance of the fuel side of the stack are necessary if the economically attractive operation of such a system without a gas cleaning system is to be realized. In further work, an electrolyte based on doped ceria was developed that enables the incorporation of Ni-GDC fuel electrodes into the co-sintered ASC. The continuation in the SynSOFC 2 project aims to further distinguish the influence of chemical and electro-chemical interactions of the cell with the contaminants.
