NiO-BaCaCeYO as a Modified Anode Material Fabricated by the Tape Casting Method.

The development of new chemically resistant anodes for protonic ceramic fuel cells (PCFCs) is urgently required to avoid the costly deep hydrogen purification method. BaCaCeYO (5CBCY), which is more chemically resistant than BaCaCeYO, was here tested as a component of a composite NiO-5CBCY anode material. A preparation slurry comprising 5CBCY NiO, graphite, and an organic medium was tape cast, sintered and subjected to thermal treatment in 10 vol.

Inkjet Printing Infiltration of the Doped Ceria Interlayer in Commercial Anode-Supported SOFCs.

Single-step inkjet printing infiltration with doped ceria CeYeO (YDC) and cobalt oxide (CoO) precursor inks was performed in order to modify the properties of the doped ceria interlayer in commercial (50 × 50 × 0.5 mm size) anode-supported SOFCs. The penetration of the inks throughout the LaSrCoFeO porous cathode to the GdCeO (GDC) interlayer was achieved by optimisation of the inks' rheology jetting parameters.

Infiltration of commercially available, anode supported SOFC's via inkjet printing.

Commercially available anode supported solid oxide fuel cells (NiO-8YSZ/8YSZ/LSCF- 20 mm in diameter) were anode infiltrated with gadolinium doped ceria (CGO) using a scalable drop-on-demand inkjet printing process. Cells were infiltrated with two different precursor solutions-water based or propionic acid based. The saturation limit of the 0.
