The performances of Intermediate Temperature Solid Oxide Fuel Cell (IT-SOFC) anode-supported planar cells with a 10 cm2 active surface were studied versus the combination of cathode thickness and the presence of an Anode Functional Layer (AFL). The temperature range was 500 to 650 °C, and Gd0.1Ce0.9O2−x (GDC) was used as the electrolyte material, Ni-GDC as the anode material, and La0.6Sr0.4Co0.2Fe0.8O3−d (LSCF48) as the cathode material. The power density, conductivity, and activation energy of different samples were determined in order to investigate the influence of the cathode thickness and AFL on the performance. These results showed an improvement in the performances when the AFL was not present. The maximum power density reached 370 mW.cm−2 at 650 °C for a sample with a cathode thickness of 50 µm and an electrolyte layer that was 20 µm thick. Moreover, it was highlighted that a thinner cathode layer reduced the power density of the cell.

Solid oxide fuel cells (SOFCs) convert a variety of fuels like hydrogen, e-gas, or biogas into electricity with high efficiency. Such fuels are interesting for reaching a production of electricity entirely from renewable energy sources. Sustainable fuels will play an important role because they are independent of fluctuating sources such as solar and wind. E-gas is a product of power-to-X concepts using electricity from renewable sources. Biogas is a renewable source and consists of 40%-70% CH 4 and 30%-60% CO 2 . One advantage of the SOFC is that direct internal reforming of biogas or other hydrocarbons is possible. Impurities like sulfur components, which are present in fuels like biogas, can have negative effects on the internal reforming of the fuel in the SOFC and the electrochemical reaction as well. These effects have been widely investigated. The current study presents a new, time-efficient approach to investigating sulfur poisoning. It analyses how the electrochemical reaction and the methane reforming process are affected by H 2 S via the evaluation of iV-curves recorded with and without sulfur. It yields the well-known parameter voltage drop occurring due to sulfur exposure.

Solid oxide fuel cells are an option to convert carbon containing fuels like natural gas or biogas into electricity with high efficiency. Natural gas consists mainly of CH4 and is based on fossil fuels nowadays but can be based on renewable sources in the future. Biogas is a renewable source and consists of 40%-70% CH4 and 30%-60% CO2. One advantage of the SOFC is that direct internal reforming of these fuels is possible. Impurities like sulfur components, which are present in both fuels, can have negative effects on the internal reforming of the fuel in the SOFC and the electrochemical reaction. These effects have been widely investigated. The current study presents a new, time efficient approach to investigate sulfur poisoning. It is possible to predict the effect of H2S expressed as the well-known voltage drop occurring due to sulfur exposure via the evaluation of iV-curves taken with and without sulfur. 10.1149/09101.0511ecst ©The Electrochemical Society ECS Transactions, 91 (1) 511-521 (2019) 511 ) unless CC License in place (see abstract). ecsdl.org/site/terms_use address.
