“…Following challenges are faced in selection of proper materials for catalysis and oxygen transport in SOFC: (a) material compatibility is an important challenge in selection of as at higher temperatures, materials experience thermal stresses at electrode-electrolyte boundary along with within themselves, (b) stability of materials at high working temperature of SOFC, and (c) corrosion resistance of materials due to high sulfur and coke content during internal reforming reactions. 51,206,207 Being a cause of most barriers in commercialization of SOFC, challenge like high working temperature has motivated researchers in past 20 years to develop materials for SOFC to work in LT range (400 C-650 C) from (700 C-1000 C). The low operating temperature will help in making SOFC more affordable and market friendly by allowing use of metallic interconnects, reduction in size of heat exchanger, and fast start-up/shut down times.…”

Summary The declining reserves and environmental concerns related to the use of fossil fuels have made the global think tanks to pursue for the technologies considered to be renewable as well as sustainable. Fuel cell technology is emerging and a green way to produce electricity, provided sufficient amount of hydrogen (fuel) is available that directly convert chemical energy to electrical energy. Despite of being an efficient and eco‐friendly source of energy, commercialization of fuel cells is still difficult to attain. Techno‐economic challenges like high manufacturing and assembly costs, water management, system size, nondurability, and instability of the system need to be addressed. In order to resolve these issues, considerable research has been carried out for the development of novel and inexpensive materials for the fuel cells. In this article, we have reviewed the development of electrodes and electrolyte materials for different types of fuel cells. A detailed description of applications, challenges, and improvement of electrodes/electrolytes materials of different types of fuel cells (polymer electrolyte membrane fuel cells, direct methanol fuel cells and solid oxide fuel cells) have been reported in this review article. A brief review of the development of materials for electrode of molten carbonate fuel cells has also been presented in the review.

“…Many research has been conducted to overcome this challenges while maintaining the high efficiency of SOFC. Recent research suggests lowering the high temperature (800 o C-1000 o C) to intermediate temperature (400 o C-700 o C) [2] to reduce the fabrication and material cost. This is carried out by using metallic interconnectors in SOFC stack cell and thin electrolyte.…”

Accidents are expected when operating Solid Oxide Fuel Cell (SOFC) unit system in a plant due to its complexity and operating conditions. SOFC system which consists of risky components such as combustor, reformer, heaters and SOFC stack poses risk of fire and explosion especially due to its high operating temperature. In addition, other factors such as failure rate components, quantity materials, gas leakage and chemical characteristics involved further increase the risks to an alarming level. In reality, these conditions are evolving depending on the current situation which make it challenging in determining the actual risks. Since SOFC technology is still emerging and not widely used, the studies on hazard identification on SOFC system is very minimal. The present work develops a new hazard evolution framework for SOFC system which is mapped into Bayesian network model using open-source software programs, GeNie to bring dynamics in identifying risks and hazards. This allow all potential hazards to be updated in real-time to ensure safe implementation of SOFC unit system in a plant. With this, all factors and evolving conditions contributing to the risks can be estimated with higher precisions to reduce the accidents probability. Sensitivity analysis is also carried out to determine how input parameters influencing the identified hazards. Results showed the probability of fire and explosion occurring in SOFC system is approximately 21% and 7% respectively. Operating conditions (temperature and pressure) are identified as the main causes contributing to the risks. Higher temperature increases risks of Fire from 17% to 21% while higher pressure increases the risks of Explosion from 7% to 18%. The current work identified the occurrence of final hazards in SOFC system dynamically and can be served as guideline for safer implementation of SOFC.

The new coronavirus (COVID-19) has started spreading all over the world. Every infected is fighting to recover a little and every health worker is fighting to save a single life in this pandemic. There is no place for patients to stay in the hospital, health workers are given all possible services to save their lives. In this situation, uninterrupted power system is needed, which can be supplied by solid oxide fuel cells (SOFCs). Therefore, solid oxide fuel cells (SOFCs) are becoming attractive day by day with competing environmentally friendly energy sources due to high energy efficiency, low emission rate and comparatively low operating cost. The purpose of this work is to investigate how copper-doped perovskite electrode materials impact the performance of solid oxide fuel cells (SOFCs) to overcome such crucial times successfully. Different synthesis process of Cu-based electrodes and analyzing electrochemical properties were investigated in this work. The evaluation was performed in terms of synthesis process, sintering temperature, lattice type and parameters, electrical conductivity, thermal expansion coefficients (TEC), polarization resistance, activation energy, and power density. In order to provide additional energy during this pandemic COVID-19, low-cost, highly performed, and durable materials are needed to make SOFC.
