Abstract
The present invention provides a solid oxide cell stack, comprising: —at least two cells which each comprise a first electrode layer, an electrolyte layer, a second electrode layer, —gas passage ways, and—sealing components, wherein the sealing components comprise a glass component and a component comprising a metal oxide or metal oxide precursor, and wherein the component comprising the metal oxide or metal oxide precursor is located at least in between the glass component and a gas passage way. The present invention further provides a method of producing the above solid oxide cell stack, comprising the steps of: —providing at least two SOC cells comprising each a first electrode layer or electrode precursor layer, an electrolyte layer, a second electrode layer or electrode precursor layer; —stacking at least two cells so as to form a cell stack including gas passage ways; and—sealing said cell stack with sealing components, wherein the sealing components comprise a glass component and a component comprising a metal oxide or metal oxide precursor, and wherein the component comprising the metal oxide or metal oxide precursor is at least located in between the glass component and a …
