A protonic ceramic fuel cell (PCFC) has great potential for medium temperature power generation. Its working process, however, is complicated and quite different from the traditional oxygen ionic solid oxide (O2?-SOFC) proton exchange membrane (PEMFC). In this paper, a multi-physical model PCFC with H+/e?/O2? mixed conducting cathode established, in which fuel- oxidant-diffusing processes; elec...

Tape casting is a well-established method for manufacturing thin ceramic layers with controllable thickness and porosity. This study investigates the potential of 10Sc1CeSZ material electrolyte anode intermediate-temperature solid oxide fuel cells (IT-SOFC) in an anode-supported cell (ASC) geometry. In order to use La0.6Sr0.4Co0.2Fe0.8 Oxide (LSCF) cathode material, Gd0.2Ce0.8 (GDC) barrier lay...

Solid oxide cells (SOCs) are high temperature energy-conversion devices, which have attracted a growing interest in the recent years. Indeed, this technology presents efficiency and good reversibility fuel cell (SOFC) electrolysis (SOEC) modes. Nevertheless, SOCs durability is still insufficient due to performance degradation during operation. In context, physics-based model has been proposed i...

To minimize alteration of the La0.6Sr0.4Co0.2Fe0.8O3−δ (LSCF)/Gd0.2Ce0.8O2−δ(CGO20)/Y0.06Zr0.94O2−δ(3YSZ) interface via strontium zirconate formation in solid oxide cells, electron beam physical vapor deposition was employed to manufacture dense, thin gadolinium-doped ceria (CGO) interlayers. CGO layers with thicknesses 0.15, 0.3, and 0.5 μm were integrated state-of-the-art 5 × cm2-large electr...

Abstract The Ce 0.8 Gd 0.2 O 2− δ (CGO) interlayer is commonly applied in solid oxide fuel cells (SOFCs) to prevent chemical reactions between the (La 1− x Sr )(Co y Fe )O 3− (LSCF) oxygen electrode and Y 2 3 -stabilized ZrO (YSZ) electrolyte. However, formation of YSZ–CGO solution with low ionic conductivity SrZrO (SZO) insulating phase still happens during cell production long-term operation,...
