Abstract
Provided are a current collector for a fuel cell and a stack structure having the same. The fuel cell includes an electrolyte layer, and an air electrode layer and a fuel electrode layer on both surfaces of the electrolyte layer and generates electricity, and the current collector includes an even surface configured to electrically surface-contact with the air electrode layer or the fuel electrode layer; and a plurality of openings punched so that air or a fuel gas directly contacts with the air electrode layer or the fuel electrode layer.
