Electrolyte-supported tubular solid oxide fuel cell manufacturing method, involves producing tubular electrolyte body using injection molding process by injecting electrolyte mass into cavity in fluent state

摘要

The method involves producing a tubular electrolyte body (10) using an injection molding process, where electrolyte mass is injected into a cavity in a fluent state. The cavity is formed by injection molding tools. A cylindrical casting core is arranged in the cavity before injection of the electrolyte mass into the cavity. A flange section (14) is formed in the electrolyte body. A support structure is located on the casting core before injection of the electrolyte mass into the cavity. The support structure is designed as a film, body with a planar extension or tubular/tube-like casing body. The support structure is formed from cellulose derivative, methylcellulose or polymer on basis of acrylic acid, maleic acid, vinyl pyrrolidone, vinylimidazole or polyvinyl alcohol. An independent claim is also included for an electrolyte-supported solid oxide fuel cell.
