PURPOSE: A fuel cell stack is provided to impart cooling effect by endoergic reacting fuel supplied from the opposite side of a micro pipe with fuel electrode material, thereby capable of reducing temperature deviation along horizontal direction of a stack. CONSTITUTION: A fuel cell stack comprises: a separator(10) in which a fuel supply hole(12), and a fuel channel part(14), which is a path for the fuel are equipped; and at least one micro pipe(22) located along the fuel channel part, of which one end is arranged in the fuel supply hole. The micro pipe is arranged, length and number are controlled in order to uniformize temperature inside the stack. The diameter of the micro pipe is shorter than the depth and the width of the fuel channel part. |
