An electrochemical cell comprising a reducing side (i.e. side of cell exposed to gases of lower oxygen potential than the opposing side) support structure containing Ni/NiO and stabilized zirconia, a reducing side electrode structure, an electrolyte struct...

An electrochemical cell with a substantially gas-tight electrolyte, designed for use between two gases, one of which is more reducing than the other (oxidant) gas, comprises a reducing side support structure containing Ni/NiO and stabilized zirconia, said ...

Process for shut-down of a high temperature fuel cell stack, the process comprising the following steps: a) connecting the fuel cell stack in parallel to a power supply unit at a predefined temperature and/or voltage of the fuel cell stack, b) applying a v...

A novel solid oxide cell consists of at least one layer containing steel (metal alloys consisting predominantly of Fe) [layer A "support"], in which the backbone of one or more layers [layer B ("anode" or "cathode")], that is located between layer A and a ...
