Abstract
A device for a solid oxide fuel cell or a solid oxide electrolysis cell includes an integral one-piece construction of a current collector and a manifold. The device eliminates the need for a brazing or thermal bonding process for joining the manifold with the current collector, and thus makes it possible to prevent breakdown of the junction formed between the manifold and the current collector, which can lead to gas leakage through the junction, and thus can be used for a long period of time.
