Abstract: A method for applying a fixed image onto at least one surface of a component in an electrochemical device is described. The component is usually formed of an alumina material. An image-forming material is first applied onto the component surface in its green state. The mark or image is applied in a desired pattern by an additive process, such as direct-write or screen-printing. The component is then heated at a sintering temperature sufficient to ensure conversion from the green state into a fired ceramic state. The sintering temperatures are also sufficient to fix the image upon the surface of the component. The image can be read by the human eye, or by various machine-readable techniques. Related methods for monitoring the location and status of a ceramic electrochemical cell component during its manufacture and during other processing steps are also described.
