“…Amphoteric electrode metal oxides easily dissolve in acidic or basic environments. Strategies to circumvent the poor stability of metal oxide electrodes involve control of the melt oxobasicity with admixtures (eg, rare earth or alkaline carbonates/oxides), but also formation of solid solutions based on conventional NiO with other metals . The state‐of‐the art solutions show some efficacy, but alternative materials with high conductivity and chemically stable are still needed.…”

Summary The optimization of the performance of electrodes (oxide‐based) for composite electrolytes (Ce0.9Gd0.1O1.95 + (Li0.52Na0.48)2CO3) is addressed in this work acting mostly on the electrode chemical nature (eg, LaCoO3, Li0.43NiO2, or LiNiO2), thickness (single and multiple screen‐printed layers), and cell layer concept (with/without barrier layers between electrode and electrolyte). The cell performance and stability were analyzed by electrochemical impedance spectroscopy, X‐ray diffraction, scanning electron microscopy, and energy dispersive spectroscopy. LaCoO3 electrodes deposited on the electrolyte using an intermediate barrier layer showed a promising area specific resistance of 0.22 Ω.cm2 at 600°C. This optimized cell processing route was adopted as reference to study the endurance performance of distinct electrode materials up to 100 hours in air, at 550°C, where lithiated NiO showed the best stability.

“…Within a significant list of tested electrode materials, the best area specific resistance (ASR) values are in the order of 0.1 Ω.cm 2 at 550°C, using a standard LiNiO 2 cathode. A few complex chemical compositions show ASR values about twice to three times higher in the 500°C to 550°C range.…”

Summary The energy crisis has reached to an alarming situation due to increase in population. To overcome the shortfall of energy, solid oxide fuel cell (SOFC) being cheap, clean, and efficient renewable energy source is getting attention for electricity generation. Out of the three main components as anode, electrolyte, and cathode; anode/fuel electrode is an important component of SOFC because it allows the flow of electrons via external circuit to cathode generating the electric current and hence requires high electrical conductivity. In this review, anode materials synthesized until now are reviewed and by careful analysis categorized on the basis of operating temperature, conductivity, electrode polarization resistance, and structure. This comparison and categorization will provide selection criteria for state‐of‐the‐art and highly efficient anode materials for SOFC. In addition, the synthesis methods have been reviewed on the basis of their pros and cons, which will further facilitate the researchers to select the best synthesis method so as to get optimized properties of materials.

Fuel cells are a promising future energy technology to provide effective conversion from fuel to electricity. Fuel cells can be utilized in a wide range of applications and over a broad power scale. To become commercially viable, major progress both in the science and technology of fuel cells is necessary. Advanced fuel cell technologies such as lowtemperature solid oxide fuel cells (SOFCs), utilization of nano-materials, improved theoretical understanding of new fuel cell materials, and better fuel cell system optimization, are examples of approaches leading to more effective technology.This Timurkutluk et al.[4] investigated the infiltration of nano-ion conductors to the anode and cathode side to improve SOFC performance. The power density could be increased even by a factor of two through the infiltration, but the particle size and the porosity affected the results.Tosto [5] analyzed mixed ionic-electronic conductivity in solid oxides in the presence of point and line lattice defects. Presence of dislocations in the crystal lattice causes a drift force additional to that due to the concentration and electric potential gradients and explains increased conductivity.Malkow et al.[6] have developed a harmonized testing procedure for polymer electrolyte membrane fuel cell power stacks using polarization measurements. The assessment of the stack performance is based on a statistical approach of the test outputs.Ferreira et al.[7] discussed composite ionic conductors for fuel cells. They found that in addition to mixed carbonate phase, unexpected composite effects may influence charge transport properties. Grain sizes and interfacial layers with nano-sized crystals also were investigated.Lund [8] analyzed poly-generation systems based on fuel cells and showed that not only the performance parameters but also the characteristics of the end-use application will determine the energy benefits. About 10-20% primary energy savings can easily be achieved with LT-SOFCs.
