PROBLEM TO BE SOLVED: To provide a manifold and a stack structure of a fuel battery in which a large thermal stress occurs hardly in the joint site between each cell and a manifold and no chromium poisoning occurs.SOLUTION: A stack structure of a fuel battery has plural cells 100 each comprising a ceramic burned body, and a manifold 200 for supplying fuel gas to each of the plural cells 100. Each cell 100 is fixed to the manifold 200 so that the plural cells 100 are arranged like a stack and the internal space of the manifold 200 and a gas flow path formed in each cell 100 intercommunicates with each other. The overall manifold 200 is formed of ceramic material. The overall manifold 200 is formed by spraying heated and melted ceramic powder and performing three-dimensional molding. That is, the overall manifold 200 may be formed by applying flame coating. |
