とができる。As described in detail above, according to the present invention,
At least two stacks of a plurality of cells each including a fuel electrode, a solid electrolyte, an air electrode and a ceramic separator are stacked.
By constructing the manifold using the two, it is possible to improve the number of pipes for supplying fuel and air as compared with the conventional ceramic fuel cell module, and thus to improve the electrode area. It is possible to obtain a high temperature fuel cell module having a simple structure that can be effectively used, can uniformly supply gas to the cell portion, and can further reduce cost.
