The definition of peat varies between soil science and engineering as well as different countries.
It is consists of undecomposed fibrous organic materials, easily identifiable and extremely acidic meanwhile sapric peat contains highly decomposed materials.
Materials and Methods Some past research had been reviewed to provide rationale data of the study and to give some information on the physical properties of the peat soil.

However, material problems associated with the high operating temperature (1000℃), which include electrode sintering, gas tight sealing, interfacial diffusion between the electrode and electrolyte, mechanical stress due to different thermal expansion coefficients of the cell components, and a limited choice of expensive interconnects, give rise to recent attention towards the prospect of SOFCs being operated at reduced temperatures (500-800 ℃ ).
The working mechanism of the mixed-gas fuel cell is based on the difference in the catalytic activity for the oxidation of the fuel between two electrode materials: one material catalyzes the fuel oxidation to form the synthesis gas while the other is inactive to this reaction [3].
To make a Sm0.2Ce0.8O1.9 (SDC) sol for the electrolyte materials, an appropriate amount of Sm(NO3)3.6H2O from Aldrich (99.9% purity) and commercial ceria sol from Alfa Aesar (20% in water) were dissolved at an atomic molar ratio of Sm:Ce = 2:8 in distilled water and ethanol.

Introduction Highly pure vitreous silica is a typical heat-resistant material.
In addition, this material has excellent electrical and optical properties.
Therefore, it is often served as multifunctional material at extremely high temperature.

Generally, these methods require expensive and sophisticated equipments, such as vacuum and preparation of target materials.
Therefore, it is important to develop new processing material methods with low costs and simple technology to prepare ITO thin films.
