SOLID OXIDE FUEL CELL STACK

摘要

PURPOSE: A solid oxide fuel cell stack and a manufacturing method thereof are provided to enlarge the size of the stack with a strong structure, to secure the high power density, and to prevent the performance degradation. CONSTITUTION: A manufacturing method of a solid oxide fuel cell stack comprises the following steps: forming unit modules by electrically connecting unit cells in parallel; and electrically and directly connecting the unit modules. The unit cells include multiple inside channels penetrating a porous cube. A coating channel coated with an electrode and an electrolyte layer is formed among the inside channels.
