Abstract:

Fuel cell is an energy converter device that generates electricity through electrochemical reaction between hydrogen and oxygen. An example of fuel cell is the solid oxide fuel cell (SOFC) which uses a ceramics based solid electrolyte. Due to the use of ceramics, SOFC normally operates at high temperatures up to 1000 °C. This high operating temperature makes SOFC known for its efficient energy conversion capability and excellent fuel flexibility. However, despite the advantages, the extreme temperatures limit the uses of SOFC. High operation temperature leads to long term operational issues in

To identify critical parameters upon variable operational temperatures in a planar SOFC, an experimentally agreeable model was established. The significance of temperature effect on the performance of SOFC components was investigated, and the effect of activation energy during the development of intermediate electrode materials was evaluated. It is found the ionic conductivity of electrolytes is identified to be unavoidably concerned in the development of the intermediate-temperature SOFC.

Abstract:

Solid oxide fuel cell (SOFC) has significant advantages of clean and quiet operation while providing a relatively high efficiency owing to enhanced reaction kinetics at high operating temperature. The high operating temperature of SOFC, typically around 800 – 1000°C helps to enable internal reforming of hydrocarbons and negate effects of impurities in small quantities in the fuel. However, this limits the application of SOFC only to stationary applications due to the long period needed to reach this temperature range. A high temperature operation is also not ideal in terms of cost reduction an

Abstract:

Intermediate temperature solid oxide fuel cell (SOFC) operation provides numerous advantages such as high combined heat and power (CHP) efficiency, potentially long-term material stability, and the use of low-cost materials. However, due to the sluggish kinetics of the oxygen reduction reaction at intermediate temperatures (500–700 °C), the cathode of SOFC requires an efficient and stable catalyst. Significant progress in the development of cathode materials has been made over recent years. In this article, multiple strategies for improving the performance of cathode materials have been extens

The main obstacle to solid oxide fuel cells (SOFCs) implementation is the high operating temperature in the range of 800–1,000 °C so that it has an impact on high costs. SOFCs work at high temperatures causing rapid breakdown between layers (anode, electrolyte, and cathode) because they have different thermal expansion. The study focused on reducing the operating temperature in the medium temperature range.

Abstract:

Many physical and chemical problems in solid oxide fuel cells (SOFC) are induced by the operating temperature of approximately 800 ~ 1000°C. The focus of the research in SOFC’s is, thus, on running the systems at the intermediate operating temperature range below 800 °C. A way to achieve this includes changing the electrolyte material in order to get a good ionic conductivity in the intermediate temperature range below 800 °C. In this work, gadolinium doped ceria is selected as the electrolyte, which was mixed with NiO for the anode material, and tape cast and laminated to produce a novel grad

Triple perovskite has been recently developed for the intermediate temperature solid oxide fuel cell (IT-SOFC). The performance of Nd1.5Ba1.5CoFeMnO9−δ (NBCFM) cathodes for IT-SOFC is investigated in this work. The interfacial polarization resistance (RP) of NBCFM is 1.1273 Ω cm2~0.1587 Ω cm2 in the range of 700–800 °C, showing good electrochemical performance. The linear thermal expansion coefficient of NBCFM is 17.40 × 10−6 K−1 at 40–800 °C, which is significantly higher than that of the electrolyte.

Doped lanthanum chromite has been the most common material used as interconnectors in solid oxide (SOFC) fuel cell, allowing for the stacking of the SOFC. Reducing the operating temperature, to around 800°C, the cells of solid oxide fuel have made the use of metal interconnectors possible as an alternative to ceramic LaCrO3. From the practical point of view for the material to be a strong candidate as an interconnector, it must have good physical and mechanical properties, such as resistance to oxidizing environments and reducers, facility to manufacture, and adequate thermomechanical properti

The cathode is one of the most important components of solid oxide fuel cells (SOFCs). The reduction of oxygen at the cathode (traditional cathodes like LSM, LSGM, etc.) is the slow step in the cell reaction at intermediate temperature (600–800[Formula: see text]C) which is one of the key obstacles to the development of SOFCs. The mixed ionic and electronic conducting cathode (MIEC) like LSCF, BSCF, etc., has recently been proposed as a promising cathode material for SOFC due to the improvement of the kinetic of the cathode reaction. The MIEC materials provide not only the electrons for the re

Natural gas appears to be a fuel of great interest for solid oxide fuel cell (SOFC) systems.

This paper proposes a model solution using the CFD-ACE software package to simulate the behavior of a tubular SOFC.
