Abstract
Official abstract text for this publication.
Initial reduction temperature of an SOC is kept higher than the highest intended operation temperature of the SOC to keep the electrolyte under compression by the Anode Support at all temperatures equal to and below the maximum intended operation temperature.
First claim
Opening claim text (preview).
1 . Process for activating an anode and an anode support comprised in a Solid Oxide Cell by reduction of the Solid Oxide Cell, the Solid Oxide Cell further comprising an electrolyte and a cathode, the process comprising the step of heating the Solid Oxide Cell to a reduction temperature higher than the maximum intended operation temperature of the Solid Oxide Cell, whereby the electrolyte is kept under compression by the anode support during operation. 2 . Process according to claim 1 , wherein the Solid Oxide Cell further comprises one or more barrier layers. 3 . Process according to claim 1 , wherein the solid Oxide cell further comprises one or more contacting layers. 4 . Process according to claim 1 , wherein the reduction temperature of the Solid Oxide Cell is above 800° C. 5 . Process according to claim 1 , wherein the reduction temperature of the Solid Oxide Cell is above 775° C. 6 . Process according to claim 1 , wherein the reduction temperature of the Solid Oxide Cell is above 750° C. 7 . Process according to claim 1 , wherein the reduction temperature of the Solid Oxide Cell is above 700° C. 8 . Process according to claim 1 , wherein the reduction temperature of the Solid Oxide Cell is above 600° C. 9 . Process according to claim 1 , wherein the reduction temperature of the Solid Oxide Cell is above 500° C. 10 . Process according to claim 1 , wherein the reduction temperature of the Solid Oxide Cell is the maximum intended operation temperature plus a temperature range, ΔT. 11 . Process according to claim 10 , wherein ΔT is 0-500° C., preferably 0-300° C., preferably 0-100° C. 12 . Process according to claim 1 , any of the preceding claims, wherein the anode support comprises a cermet of NiO and YSZ and the activation is done by reducing the NiO into Ni. 13 . Process according to claim 1 , wherein the CTE of the electrolyte is lower than the CTE of the anode support. 14 . Solid Oxide Cell produced in a process according to claim 1 , wherein the electrolyte of the cell is kept under compression by the anode support at all temperatures at, and below the reduction temperature.
