Abstract: An electrochemical cell includes: a positive current collector in which an injection part, an ejection part and a passage are defined, where air including an oxygen is injected through the injection part, an exhaust gas is ejected though the ejection part ejecting, and the passage defines a single path which connects the injection part and the ejection part; and a unit cell disposed to be adjacent to the positive current collector. The unit cell includes a positive electrode layer, an active material of which is the oxygen gas, a negative electrode metal layer disposed on an opposite to the positive current collector with respect to the positive electrode layer, and an electrolyte membrane interposed between the positive electrode layer and the negative electrode metal layer.
