Method for manufacturing a solid oxide fuel cell device

A method for manufacturing a solid oxide fuel cell device comprising a cell array including a plurality of individual fuel cells housed in a fuel cell module, and a current collector electrically connected to electrodes formed on the end portions of the plurality of individual fuel cells constituting the cell array, comprising:

• a step for respectively forming electrically conductive electrode protective layers on electrodes formed on the end portions of the plurality of individual fuel cells;
• after the step for respectively forming electrically conductive electrode protective layers, a step for arranging the plurality of individual fuel cells in the form of a cell array;
• and
• after the step for arranging the plurality of individual fuel cells in the form of the cell array, an attaching step for attaching a current collector to the cell array, wherein the current collector is a metal plate in which a plurality of attaching holes are formed for respectively inserting the end portions of the plurality of individual fuel cells, a plurality of elastic pieces are provided at each attaching hole, and by pressing the current collector into the cell array, the end portions of the individual fuel cells are inserted into the corresponding attaching holes of the current collector, and the current collector is attached to the cell array by the elastic force of the elastic pieces;
• wherein the electrode protective layer is constituted to prevent damage to the electrode caused by contact of the elastic pieces in the attaching step, and after the current collector is pressed into the cell array in the attaching step, the elastic pieces engage with the electrode protective layers.
