PURPOSE: A fuel battery stack is provided to prevent degradation of mechanical strength of electrolyte membrane generable by excessive phosphoric acid impregnated in an electrolyte membrane. CONSTITUTION: A fuel battery stack comprises: one or more membrane-electrode assembly(10) comprising an electrolytic membrane(12), an anode electrode(13) arranged on a first side of the electrolyte membrane, a cathode electrode arranged on a second side which is an opposite side of the first side; a supply element(50) supplying a conductive material by being combined to the electrolyte membrane. The supply element comprises a first supply member which can contact to the first side of the electrolyte membrane, and a second supply member which can contacted to the second side of the electrolyte membrane. |
