Abstract: A solid oxide electrochemical cell includes a solid oxide electrolyte, a fuel-side electrode located on a first side of the solid oxide electrolyte, and an air-side electrode located on a second side of the solid oxide electrolyte. The air-side electrode includes a strontium getter material, a current collector layer and a functional layer located between the current collector layer and the second side of the solid oxide electrolyte.

Abstract: An interconnect for an electrochemical cell stack, the interconnect including an interconnect substrate having an air side and an opposing fuel side, and a protective layer coated on at least the air side of the interconnect, the protective layer including a transition metal oxide including copper (Cu) and at least one of iron (Fe) and manganese (Mn).

Abstract: A method of forming a protective layer on an interconnect for an electrochemical cell stack includes coating at least one side of the interconnect with a metal oxide powder to form a protective layer, sintering the coated interconnect in an inert atmosphere to at least partially reduce the protective layer, and oxidizing the sintered interconnect in an oxidizing atmosphere to oxidize and densify the protective layer.

Abstract: A method of forming a protective coating on an interconnect for an electrochemical device stack includes providing a powder on the interconnect and laser sintering the powder.

Abstract: A method in which a concentration of a chemical species of interest is obtained. The method comprises measuring a property (e.g. the oxidation reduction potential) of a reagent (typically based on a simple single electron redox couple) to obtain a baseline measurement. The reagent is mixed with the solution under test, then the property of the mixture is measured to obtain a post reaction measurement. Then the concentration of the chemical species of interest is determined based on the baseline measurement and the first post reaction measurement, typically by calculating a difference of the baseline measurement and the post reaction measurement, then using the difference and a pre-determined conversion table to determine the concentration of the chemical species of interest.
