“…After oxidation at 500 • C, the NiO-GDC 10 substrate shows grain boundary (GB) and grain interior (GI) conductivities at 0.107 and 0.0009 S cm −1 , respectively. The activation energies calculated from the Arrhenius plots for the GI and GB conductivities are 0.81 and 0.9 eV, respectively [32]. Figure 6a also shows the characteristic of the µ-SOFC at different operating temperatures.…”

A novel micro-solid oxide fuel cell (µ-SOFC), with a rectangular saw-tooth shape, was designed with a 50 wt% BYCF + 50 wt% GDC 10 cathode and a 60 wt% NiO + 40 wt% GDC 10 anode deposited on a GDC 10 electrolyte substrate by the spray pyrolysis technique. µ-SOFC receives methane only (CH 4) as fuel gas from one side. The fuel gas was applied at a flow rate of 0.2 l min −1. The power density obtained was 1.0 µW at 800 • C. Voltage levels generated by the µ-SOFC at 40-99.99% CH 4 was highly accurate representing the quantity of CH 4. Low accuracy was observed at 10-30% of CH 4. Therefore, µ-SOFC is an application of SOFC technology to be a sensor for economically detecting CH 4 in a biogas system, while being capable of operating in humid conditions at high temperatures.

“…The thickness of the films grown by this method was found to be 13 μm. The grain interior (GI) conductivity of the half-cell fabricated in this study was 0.1 S cm À1 at 500 C, which is well-desired for IT-SOFC [187]. Lee et al have carried out an experimental study combined with theoretical simulations to understand the effect of mechanical strain on the electrical properties of GDC thin films [193].…”

“…These GDC thin film electrolytes have been fabricated by different deposition techniques including MBE [172], PLD [173,177,179,180], magnetron sputtering [133,175,181,182], chemical vapor deposition (CVD) [183][184][185], electron beam vapor deposition [186], spray techniques [174,187], solid state reaction [176], tape casting [163], spin coating [178], and sol-gel process [188]. Some of the selected GDC electrolytes fabricated by these techniques will be discussed here.…”

“…The 3 μm thick electrolyte exhibited an ionic conductivity of 2.58 Â 10 À3 S cm À1 at 700 C with activation energy of 0.34 eV. Chourashiya and Jadhav have synthesized GDC thin films on NiO-GDC anode substrate using spray [187]. However, they observed that GDC thin films were non-adherent to ceramic substrate.…”

“…The heat treatment transformed NiO-GDC substrate to Ni-GDC and produced a rough and porous substrate surface, which may improve the adhesion of GDC to the substrate. However, SPT thin film deposition on metallic substrates was quite difficult, therefore the GDC synthesis method was modified [187]. The thickness of the films grown by this method was found to be 13 μm.…”

State-of-the-art solid oxide fuel cells (SOFC) are among the main candidates for clean energy technology due to their high efficiency, fuel flexibility, low air pollution, and minimal greenhouse gas emission. However, high operational temperature of SOFC is a greater challenge in commercialization of these devices for low cost and portable applications. High temperature operation of SOFC degrades its performance with aging, limits the selection of materials for fuel cell components, and increases the fabrication cost. Thus, there have been enormous efforts to improve the properties of existing materials and develop new materials for SOFC components in order to lower the operating temperature of SOFC. Recent advances in thin film technology have also been utilized to develop new materials with improved properties for SOFC. One of the key components in SOFC is the electrolyte and several research groups are working on developing new electrolyte materials. In this chapter, we will discuss the recent advances in thin film SOFC electrolytes. This extensive discussion includes the evolution of doped ceria, doped zirconia, and multilayer hetero-structured thin film electrolytes. The newly developed nanoscale thin films and multilayer hetero-structures with improved oxygen ionic conductivity will have significant impact on SOFC devices. Introduction Background of Solid Oxide Fuel Cells (SOFC)The latest U.S. energy reviews revealed that more than 80 % of the energy consumed in the world is still produced by non-renewable energy sources such as petroleum, natural gas, and coal [1]. Moreover, it is projected that world energy consumption will grow by 56 % from 2010 to 2040. Therefore, from a long-term energy perspective, clean energy technologies are needed to utilize primary energy
