ABSTRACT:
A power generating device in which a plurality of cylindrical solid oxide fuel cell elements are electrically connected to each other to constitute a collecting cell which is provided in a power generating chamber. The device is arranged such that a fuel gas is supplied on the surface of each solid oxide fuel cell element in the power generating chamber in an evenly distributed manner in order to reduce a temperature gradient due to a fuel concentration gradient in the chamber. Cracks are prevented in the solid oxide, unevenness of an electrochemical reaction in the power generating chamber becomes small, and the power generating efficiency is improved.
