Introduction Steam reforming is a process that converts hydrocarbon fuels into hydrogen and oxygenated carbon species. This process is important for catalytic hydrogen production and for direct electrochemical reforming of hydrocarbons over high temperature fuel cells, such as Solid Oxide Fuel Cells (SOFCs). One of the main problems associated with the process is that conventional reforming (el...

This work focuses on understanding the oxygen-ion transport through mixed Grain Boundaries (GBs) present in yttria-stabilized zirconia (YSZ), a common solid oxide fuel cells (SOFCs) electrolyte.

The performance, long-term durability, and thermal cycling tolerance of metal supported solid oxide fuel cells (MS-SOFCs) operating with natural gas reformate fuels is assessed. Symmetric MS-SOFCs composite SDC-Ni anode catalysts PrOx cathode are operated simulated steam-reformate partial-oxidation-reformate 1 ppm 5 sulfur. Cells for 1000 h initial degradation rates similar to humidified H2, pe...

Rare-earth tungstates with general composition “Ln6WO12” have attracted great attention in last few years due to their relatively high mixed protonelectron conductivity [1, 2]. One of the main advantages of these electrolytes, compared to the traditional perovskites based on BaCeO3, is that they exhibit high tolerance towards CO2 and H2S environments. Therefore, this material is a potential ele...

Solid Oxide Fuel Cells (SOFCs) can convert chemical energy into electrical energy, with high conversion rate, safe operation, no pollutant emissions, and is one of the most potential new power generation devices in future. However, at low medium temperature (below 800℃), cathode impedance SOFCs will increase sharply, resulting adverse effects on cell performance. Finding materials that work key...
