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 ...
We present a SOFC stack technology based on the unique SOFConnex™ concept. It uses flexible gas distribution layers between metal sheet interconnects and thin ASE cells (Ni-YSZ anode supported, thin electrolyte). Flexibility is given both in material and d ...
Electrical output behaviour obtained on solid oxide fuel cell stacks, based on planar anode supported cells (50 or 100 cm2 active area) and metallic interconnects, is reported. Stacks (1–12 cells) have been operated with cathode air and anode hydrogen flow ...
Dye-sensitized solar cells (DSC), introduced by O'Regan and Grätzel in 1991, are a low cost alternative to conventional silicon photovoltaic cells, the latter requiring extremely pure starting materials and sophisticated production procedures. DSC's, based ...
We report on small-scale experiments of simple, repeated asset markets in two risky securities and one risk-free security. As in large-scale experiments, steady convergence towards the CAPM is discovered, but the process is slower and convergence halts bef ...
The perovskite-type mixed oxide La0.3Sr0.55Ti0.95Ni0.05O3−δ (LSTN) is demonstrated to exhibit the remarkable property of structural regeneration, where Ni can be reversibly exsoluted from the host perovskite lattice resulting in a regenerable Ni catalyst f ...
