Results on solid oxide fuel cell stacks tested at 800° C with H2 fuel and using planar Ni-zirconia anode supported cells, 80x80x0.2 mm in size, are presented. Modeling and numerical simulation is used to interpret observed results and develop improved desi ...
The temperature profile generated by a thermo-electro-chemical model was used to calculate the thermal stress distribution in a tubular solid oxide fuel cell (SOFC). The solid heat balances were calculated separately for each layer of the MEA (membrane ele ...
Using petrol as a main source of energy, during the 20th century, has caused considerable amounts of damage among which are atmospheric pollution and global warming. At the same time, many geologists and economists expect that the discovery rate of new pet ...
The disintegration of the carbon anodes during the electrolysis of alumina produces dust particles contaminating the electrolytic bath. This phenomenon, called dusting, is one of the most deleterious Al electrolysis failures, as it leads to a significant d ...
The properties of sealing materials are important for the performance and reliability of solid oxide fuel cells (SOFC). Even if the properties of a sealing material can be studied separately, it remains difficult to quantify the effect of an imperfect seal ...
We optimize the preparation of BZY20 and BCY10 by a wet chemistry route (the polyacrylamide gel process) and mixed oxide route, respectively. For both materials, the purity of powders drastically depends on the annealing conditions of the raw materials. Pu ...
The effect of electrochem. promotion of catalysis or nonfaradaic electrochem. modification of catalytic activity or electropromotion was studied for the model reaction of ethylene oxidn. on sputter-coated Rh films. The thin (40 nm) Rh films were deposited ...
Reliability of SOFC stacks is a complex and key issue. This paper presents a simulation study including some degradation processes, namely, interconnect degradation and the anode reoxidation potential. Quantification for these phenomena has been included i ...
