Low-Cost Single-Step Co-Firing Technique for SOFC Manufacturing

Characteristics of SOFC single cells with anode active layer via tape casting and co-firing

“…However, they are not used widely in the fabrication of thin electrolytes (below 10 mm) and single cells that operate in an intermediate temperature range, due to the difficulties in obtaining both a thin electrolyte layer with no gas permeability and successful co-fired single cells without processing defects (wrapping, delamination, cracks, etc.) [15,16]. Recently, a successful fabrication of anode-supported electrolytes via tape casting and co-firing with a thin (5 mm) electrolyte for operation under intermediate temperatures was reported by our group [17].…”

An Anode-Supported Solid Oxide Fuel Cell (SOFC) Half-Cell Fabricated by Hybrid 3D Inkjet Printing and Laser Treatment

“…For joint sintering of the anode and electrolyte layers, a modified co-firing technique was used, which allows a temperature gradient inside the sample to be eliminated and controls the shrinkage of the individual layers. The latter allows for reducing the distortion of the structure [37]. The general scheme of the printing unit of a hybrid inkjet printer is shown in Figure 1a.…”
