The present invention provides a graded multilayer structure, comprising a support layer () and at least 10 layers () forming a graded layer, wherein each of the at least 10 layers () is at least partially in contact with the support layer (),

Horizontally graded structures for electrochemical and electronic devices

The invention provides a method of making a magnetic regenerator for an active magnetic refrigerator, the method comprising: forming a magnetic regenerator from a slurry or a paste containing a magnetocaloric material the magnetic regenerator being formed to have plural paths therethrough for the flow of a heat transfer fluid; and varying the composition of the magnetocaloric material so that the magnetic transition temperature of the magnetic regenerator varies along the paths.

Magnetic regenerator, a method of making a magnetic regenerator, a method of making an active magnetic refrigerator and an active magnetic refrigerator

The invention provides a refrigeration device, comprising: a magnetic field source; a magnetocaloric bed, one of the magnetocaloric bed and the magnetic field source being arranged to substantially surround the other, the magnetocaloric bed being arranged for relative rotation with respect to the magnetic field source such that during said relative rotation, the magnetic field experienced by parts of the magnetocaloric bed varies; plural pathways formed within the magnetocaloric bed for the flow of a working fluid during the relative rotation between the magnetocaloric bed and the permanent magnet; and a flow distributor placed at each end of the magnetocaloric bed, for controlling the part of the magnetocaloric bed able to receive working fluid during a cycle of operation.

Refrigeration device and a method of refrigerating

SOFC cell comprising a metallic supportending in a substantially pure electron conducting oxide, an active anode layerconsisting of doped ceria, ScYSZ, Ni&#x2014;Fe alloy, an electrolyte layerconsisting of co-doped zirconia based on oxygen ionic conductor, an active cathode layerand a layer of a mixture of LSM and a ferrite as a transition layerto a cathode current collectorof single phase LSM. The use of a metallic support instead of a Ni&#x2014;YSZ anode support increases the mechanical strength of the support and secures redox stability of the support. The porous ferrite stainless steel ends in a pure electron conducting oxide so as to prevent reactivity between the metals in the active anode which tends to dissolve into the ferrite stainless steel causing a detrimental phase shift from ferrite to austenite structure.
