“…These carbonate ions participate in anode reaction, making the fuel cell performance more optimal. 250 High operating temperature and carbon dioxide utilization in MCFC make them highly efficient carbon capture devices. Moreover, exhaust flue gases from MCFC contain high amount of energy in the form of sensible heat, which can be utilized by gas turbines in cogeneration systems for generation of heat and electricity.…”

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.

“…16,17 In addition, the LiOH/Li covering the surface of electrolyte particles could reduce the electronic conductivity. 18 Therefore, the cells give open circuit voltage (OCV) over 1.0 V despite the porous electrolyte. Moreover, the formation of LiOH/Li 2 CO 3 as the amorphous layer on the electrolyte particle surface builds interface conduction between the electrolyte and LiOH/Li 2 CO 3 , probably leading to the major improvement of ionic conduction and cell performance.…”

Ceramic fuel cells (CFCs) employing lithium compounds, that is, Ni 0.8 Co 0.15 Al 0.05 LiO 2 (NCAL) as symmetrical electrodes demonstrate remarkable ionic conductivity and power density at a temperature range of 400−600 °C. However, the stability issue of this type of CFCs has not been well investigated. In this work, we have demonstrated a commercially available samarium oxide (CSM) via a sodium doping method, that is, Nadoped samarium oxide (NDS) materials as functional electrolytes for robust CFCs. Results disclose that during the fuel cell operation, CSM could in situreact with LiOH from the NCAL anode to cause cell degradation. Doped sodium ions in NDS could confine the LiOH that forms at the grain boundaries, which can result in several benefits, for example, to make the NDS electrolyte denser to prevent gas leakage, to enhance the CFC performance, and to ensure the CFC stability without the need for hightemperature sintering. The NCAL/NDS/NCAL-based fuel cell delivers a stable open circuit voltage over 1.0 V and maximum power density around 200 mW cm −2 for 144 h at 500 °C. Moreover, the optimized cell gives a stable power density of 140 mW cm −2 for 75 h at 500 °C. This work presents a methodology for developing advanced low-temperature CFCs using commercial samarium oxide as the functional electrolyte.
