BACKGROUND

Exemplary embodiments pertain to the art of electrochemical cells, more particularly, to a method of making an electrochemical cell using suspension plasma spray.

Oxide fuel cells have many potential applications. For example, in the aerospace industry, potential applications include electrolysis, auxiliary power generation, and aircraft propulsion. For example, solid oxide fuel cells are compatible with hydrocarbon fuels, such as methane, ethanol, and jet fuels. Metal-supported electrochemical cell stacks, enabled by proton-conducting electrolyte materials, can also provide fast startup times, fast transit response, and high power density. However, solid oxide fuel cell technology is often very costly to manufacture.

Therefore, there is a need to develop a method of manufacturing electrochemical fuel cells, such as solid oxide fuel cells, which is more efficient and less costly.

BRIEF DESCRIPTION

Disclosed is a method of making an electrochemical cell, comprising: depositing an anode layer on a surface of a porous metal support layer; depositing an electrolyte layer on a surface of the anode layer, wherein the electrolyte layer is deposited via suspension plasma spray, wherein the electrolyte layer conducts protons; and depositing a cathode layer on a surface of the electrolyte layer.

Also disclosed is a stack comprising two or more of the electrochemical cell.
