A parallel magnetic refrigerator assembly, includes at least two magnetocaloric stages arranged in parallel connection, each having in use a cold side and a hot side; each magnetocaloric stage including hot and cold side heat exchange circuit for carrying a heat exchange fluid to respectively receive and transfer heat from the magnetocaloric stages; wherein the hot and cold side heat exchange circuit are configured such that in use a heat exchange fluid passes in thermal contact with the respective hot and cold sides of both magnetocaloric stages. The magnetocaloric stages have substantially the same temperature spans but different cold end and hot end temperatures. In this way the device temperature span may be substantially larger than the individual temperature span of each magnetocaloric stage.

A reversible SOFC monolithic stack is provided which comprises: 1) a first component which comprises at least one porous metal containing layer () with a combined electrolyte and sealing layer on the porous metal containing layer (); wherein the at least one porous metal containing layer () hosts an electrode; 2) a second component comprising at least one porous metal containing layer () with a combined interconnect and sealing layer on the porous metal containing layer; wherein the at least one porous metal containing layers hosts an electrode. Further provided is a method for preparing a reversible solid oxide fuel cell stack. The obtained solid oxide fuel cell stack has improved mechanical stability and high electrical performance, while the process for obtaining same is cost effective.
