The present invention provides a solid oxide cell comprising a support layer, a first electrode layer, an electrolyte layer, and a second cathode layer, wherein at least one of the electrode layers comprises electrolyte material, a catalyst and agglomerated particles selected from the group consisting of alkali oxides, earth alkali oxides and transition metal oxides.

Removal of impurity phases from electrochemical devices

The present invention provides a solid oxide cell stack, comprising: &#x2014;at least two cells which each comprise a first electrode layer, an electrolyte layer, a second electrode layer, &#x2014;gas passage ways, and&#x2014;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: &#x2014;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; &#x2014;stacking at least two cells so as to form a cell stack including gas passage ways; and&#x2014;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 gas passage way.

Composite glass seal for a solid oxide electrolyser cell stack

A solid oxide cell obtainable by a process comprising the steps of: depositing a fuel electrode layer on a fuel electrode support layer; depositing an electrolyte layer comprising stabilized zirconia on the fuel electrode layer to provide an assembly of fuel electrode support, fuel electrode and electrolyte; optionally sintering the assembly of fuel electrode support, fuel electrode and electrolyte together to provide a pre-sintered half cell; depositing on the electrolyte layer of the pre-sintered half cell one or more oxygen electrode layers, at least one of the oxygen electrode layers comprising a composite of lanthanum-strontium-manganite and stabilized zirconia to provide a complete solid oxide cell; sintering the oxygen electrode layers together with the pre-sintered half cell to provide a sintered complete solid oxide cell; and impregnating the one or more oxygen electrode layers of the sintered complete solid oxide cell with manganese to obtain a manganese impregnated solid oxide cell.
