Patent ID: 7721438

Claim:
An assembling method for an assembly wherein a cell structure is housed and held in a metal vessel via a compressible material having a cushioning property, said method comprising: using ink to record information onto an outside surface of a cell structure, the recorded information regarding an outside dimension of the cell structure; applying a transparent water-repellent liquid onto said recorded information; applying; a catalyst-containing liquid onto inside surfaces of the cell structure; heat-treating the cell structure at a temperature of 400 to 800° C. to fix the catalyst to the cell structure; checking said recorded information on the outside surface of the cell structure with an image analyzer; reading said recorded information; determining an inside dimension for a metal vessel based on the recorded information read from the outside surface of the cell structure; forming the metal vessel to a predetermined dimension larger than that indicated by said recorded information; surrounding an outer periphery of the cell structure with the compressible material; surrounding the cell structure and compressible material with the metal vessel having the predetermined dimension larger than that indicated by said recorded information before the metal vessel is sized to the determined inside dimension through pressure applied to the outside surface of the metal vessel; and then fixing the cell structure and compressible material in a compressed state in the metal vessel by sizing the metal vessel using one of a shrinking method and a rotary forging method to reduce an inside diameter of the metal vessel to the determined dimension.
