“…The aim of this study was to investigate the influence of experimental parameters, especially flow composition, in our testing bench conditions. More comprehensive studies on SCFC working principle were reported by Hibino [1] and Haile [7]. In the present paper, we present our recent results concerning SCFC developments, with GDC electrolyte, Ni-GDC anode and LSM or SSC or BSCF as cathode.…”

“…Their operating principle is based on the different catalytic activities of anode and cathode: ideally, the anode has to be active for the oxidation of fuel while the cathode should only present a strong electro-activity for oxygen reduction. Most significant and initial developments of SCFC devices were performed by T. Hibino and co-workers who proposed a review on SCFC in [1]. In the first developments of SCFC devices [2][3][4], materials used in conventional SOFC were used, namely YSZ for electrolyte, Ni-YSZ cermet anode and LSM (La 0.8 Sr 0.2 MnO 3 ) cathode.…”

International audienceSingle Chamber Solid Oxide Fuel Cells (SCFC) have been prepared using an electrolyte as support (Ce0.9Gd0.1O1.95 named GDC). Anode (Ni-GDC) and different cathodes (Sm0.5Sr0.5CoO3 (SSC), Ba0.5Sr0.5Co0.2Fe0.8O3 (BSCF) and La0.8Sr0.2MnO3 (LSM)) were placed on the same side of the electrolyte. All the electrodes were deposited using screen-printing technology. A gold collector was also deposited on the cathode to decrease the over-potential. The different materials and fuel cell devices were tested under propane/air mixture, after a preliminary treatment under hydrogen to reduce the as-deposited nickel oxide anode. The results show that SSC and BSCF cathodes are not stable in these conditions, leading to a very low open circuit voltage (OCV) of 150 mV. Although LSM material is not the more adequate cathode regarding its high catalytic activity towards hydrocarbon conversion, it has a better chemical stability than SSC and BSCF. Ni-GDC-LSM SCFC devices were elaborated and tested; an OCV of nearly 750 mV could be obtained with maximum power densities around 20 mW cm–2 at 620 °C, under air–propane mixture with C3H8/O2 ratio equal to 0.53

“…For stability tests of LAMOX compounds in propane:air mixture, we used a 16:84vol% propane:air proportion (above UEL), in propane excess relative to the optimal 10:90vol% propane:air proportion used in single-chamber SOFC [15,16], in order to accelerate ageing while avoiding explosivity risks. In addition, the effect of nitrogen inerting (initial mixture diluted twice in nitrogen) and water vapor (around 2-3%, from gas bubbling in water) were measured.…”

Tests for the Use of La₂Mo₂O₉‐based Oxides as Multipurpose SOFC Core Materials

International audienceThe mixed ionic-electronic conductivity under dilute hydrogen, the stability and the catalytic activity under propane:air type mixtures of a series of LAMOX oxide-ion conductors have been studied. The effect of exposure to dilute hydrogen on the conductivity of the -La2(Mo2 - yWy)O9 series at 600 °C depends on tungsten content: almost negligible for the highest (y = 1.4), it is important for La2Mo2O9 (y = 0). In propane:air, all tested LAMOX electrolytes are stable at 600-700 °C, but get reduced when water vapour is present. La2Mo2O9 is the best oxidation catalyst of the series, with an activity comparable to that of nickel.The catalytic activity of other tested LAMOX compounds is much lower, (La1.9Y0.1)Mo2O9 showing a deactivation phenomenon. These results suggest that depending on composition, La2(Mo2 - yWy)O9 compounds could be either electrolytes in single-chamber SOFC and dual-chamber micro-SOFC (y = 1.4) or anode materials in dual-chamber SOFC (low y) or oxidation catalysts in SOFCs operating with propane (y = 0)

“…Electrically insulating members prevent the current collector from being in electrical contact with the anode. Single-chamber SOFCs (SC-SOFCs) offer to reduce SOFC costs by downsizing and lowering the operating temperature [36]. Fuel utilisation and cell efficiency of real SC-SOFCs are usually much lower than 10% [37].…”

High-temperature solid oxide fuel cells (SOFCs) are considered as suitable components of future large-scale clean and efficient power generation systems. However, at its current stage of development some technical barriers exists which limit SOFC's potential for rapid large-scale deployment. The present article aims at providing solutions to key technical barriers in SOFC technology. The focus is on the solutions addressing thermal resistance, fuel reforming, energy conversion efficiency, materials, design, and fuel utilisation issues.
