In Nature, many vital biological processes take place across the interface formed between two dielectric media. For instance, photosynthesis and aerobic respiration involve a series of redox reactions occurring across energy-transducing membranes, in charg ...
The shortage of natural resources, rising energy demands and global warming have created an urgent need for more efficient energy conversion devices and different energy resources to achieve a more sustainable and efficient economy. Solid Oxide Fuel Cells ...
Nickel oxide and yttria doped zirconia composite strength is crucial for anode-supported solid oxide fuel cells, especially during transient operation, but also for the initial stacking process, where cell curvature after sintering can cause problems. This ...
This work aimed to set new guidelines for the quantification of Cr accumulation in solid oxide fuel cell cathodes after operation, and enabled to pinpoint a diffusion-controlled tolerance to Cr-poisoning for increased cathode thickness; the additional cath ...
Polarization characteristics of the electrodeposition processes of Fe powders from different citrate electrolytes and the morphology of the obtained powders were investigated. The effect of complexing agents on the cathodic polarization, the current effici ...
The common technology for solid oxide fuel cells (SOFC) is based on a cermet (ceramic-metal composite) anode of nickel with yttria stabilized zirconia (YSZ), often used as the supporting structure. One of the main limitations of this technology is the tole ...
The common technology for solid oxide fuel cells (SOFC) is based on a cermet anode of nickel with yttrium stabilized zirconia (YSZ), often used as the supporting structure. One of the main limitations of this anode technology is the redox tolerance. In thi ...
The limited fossil fuel resources and the increasing levels of greenhouse gases in the atmosphere are the driving forces in the research of alternative ways of energy production and storage. The use of solar energy is expected to grow as our society claims ...
Micro-fabricated solid oxide fuel cells (µSOFCs) are finding an increasing interest as potential power sources for portable devices such as MP3 players or laptops. The aim of this work was to fabricate a µSOFC demonstrator that works at 500°C and is fuelle ...
Tuning of the catalytic reaction rate by electric polarization of the interface between an electron conducting catalyst and an ion conducting support, called electrochemical promotion of catalysis (EPOC), is most often fully reversible. Its state-of-the-ar ...
