    Despite similar structure and cathode morphology of the cells studied, the thin film solid oxide fuel cell with the ZrO{sub 2} thin film electrolyte by the thermal ALD at °C exhibited the highest power density (38 mW/cm{sup 2}) because of the lowest average grain size at cathode/electrolyte interface.}, doi = {/}, journal. The cathode pore size, grain size, and porosity were not integrated in the PNNL model, therefore, an analytical solution for exchange current density from Deng and Petric (, “Geometric Modeling of the Triple-Phase Boundary in Solid Oxide Fuel Cells,” J. Power Sources, , pp. –) was utilized to optimize their effects on.

    Solid-oxide fuel cells are devices for the efficient conversion of chemical energy to electrical energy and heat. Research efforts are currently addressed toward the optimization of cells operating at temperatures in the region of °C, known as intermediate-temperature solid-oxide fuel cells, for which materials requirements are very stringent. In addition to the requirements . the cell resistance in anodesupported solid oxide fuel cells-, J. Electrochem. Soc. Grain-Size Effects in YSZ Thin-Film Electrolytes, J. Am. Ceram.

Power Sources– () Google ScholarCited by: 1. The oxide ionic diffusion (J) across the electrodes (cathode to anode) can be increased if the electrolyte thickness is lowered as the oxide ion diffusion in the thin-film electrolyte is inversely proportional to the thickness of the electrolyte (distance of between the electrodes) () J = σ × OCV L where σ and OCV are the ionic Author: S.

Ajith Kumar, P. Kuppusami. We have investigated the deposition of 91% ZrO2 − 9% Y2O3 thin films by a variety of sputtering techniques for the application as electrolytes in thin film solid oxide fuel cells.

The chapter describes modern nanomaterials and designs for solid oxide fuel cells (SOFCs), including cathode, anode, interconnect and electrolyte materials. The chapter then discusses the trend towards miniaturization and lowering of the operating temperatures of SOFCs.

It then describes new advances and tools for rational SOFC material design. Cathode. The cathode is the SOFC electrode where electrochemical reduction of oxygen occurs. For this, the cathode must have: (1) adequate porosity (approximately %) to allow oxygen diffusion; (2) chemical compatibility with the other contacting components (usually the electrolyte and interconnect) under operating conditions; (3) a thermal expansion coefficient.

Ag paste is often used in solid oxide fuel cells (SOFCs) as the current collector. This study investigates the effect of lead oxide (PbO), which is us. Nanocrystalline La 1‐x Sr x CoO 3‐δ (LSC) thin films with a nominal Sr‐content of x = were deposited on Ce Gd O electrolyte substrates using a low temperature sol‐gel process.

The structural and chemical properties of the LSC thin films were studied after thermal treatment, which included a calcination step and a variable, extended annealing time at °C. The grain size effect of LaSrGaMgO3-δ (LSGM) electrolyte thin film was investigated in order to clarify the mechanism of the change of ion conductivity of thin film.

Ceria-based solid oxide fuel cells (SOFCs) are the promising candidates for the low- and intermediate-temperature SOFCs.

However, the Ce⁴⁺ in the ceria-based electrolyte. Table lists the main ALD precursors and process conditions for fabricating metal oxide film–based electrolytes for fuel cells. As mentioned in the introductory topic, YSZ films have been widely used as ceramic electrolytes for various high-temperature electrochemical systems, including SOFCs, SOECs, and gas sensors [12,20,21].The main reason for their widespread use is that YSZ films.

Cu-substituted Ca3(Co1−xCux)2O6 (x = 0, ) are prepared and evaluated as cathode materials for solid-oxide fuel cells (SOFCs).
