“…On the other hand, very few attempts have been made to deposit oxide particulates on nonconducting substrate. Will et al 10 and Kobayashi et al 11 carried out EPD on reduced anode substrate where the NiO is first converted to metallic Ni and make the anode substrate conductive. In another approach, attempt has been made to mix sufficient amount of conducting graphite to make the anode conductive and suitable for EPD.…”

Thin films of 8 mol% yttria stabilised zirconia (YSZ) electrolyte have been deposited on nonconducting porous NiO-YSZ anode substrates using electrophoretic deposition (EPD) technique. Deposition of such oxide particulates on non-conducting substrates is made possible by placing a conducting steel plate on the reverse side of the presintered porous substrates. Thickness of the substrates, onto which the deposition has been carried out, varied in the range 0?5-2?0 mm. Dense and uniform YSZ thin films (thickness: 5-20 mm) are obtained after being cofired at 1400uC for 6 h. The thickness of the deposited films is seemed to be increased with increasing porous substrate thickness. Solid oxide fuel cell (SOFC) performance is measured at 800uC using coupon cells with various anode thicknesses. While a peak power density of 1?41 W cm 22 for the cells with minimum anode thickness of 0?5 mm is achieved, the cell performance decreases with anode thickness.

“…This paper reports a different approach from the early papers that combines EPD with a cosintering process. Co-sintering has recently been investigated as a promising technique for the reduction of the number of thermal cycles needed for the preparation of SOFCs [16,17]. However, usually substrates are pre-fired at an intermediate temperature prior to deposition and co-sintering.…”

Co-Sintering of Dense Electrophoretically Deposited YSZ Films on Porous NiO-YSZ Substrates for SOFC Applications

et al. 2004

An original process for the preparation of YSZ dense films with a thickness lower than 10 µm over NiO-YSZ substrates is presented. This process involves the preparation of a green membrane of NiO-YSZ and subsequent electrophoretic deposition (EPD) of commercial YSZ powder on this polymer-rich membrane. A single thermal treatment allowed removal of the organic compounds, sintering of the layers and full densification of the electrolyte.

“…The most developed and cost-effective are methods based upon supporting electrolyte powders with addition of organic binders and dispersants via screen-printing (Souza et al, 1998), tape casting (Kobayashi et al, 2002) or slurry coating technique (Jung et al, 2007). Thus supported «green» layers are sintered at temperatures ~ 1400˚ .…”
