PURPOSE: A fuel cell is provide to reduce contact resistance between an air electrode current collector and a separator or a second separator and a fuel anode current collector, thereby improve efficiency and lifetime. CONSTITUTION: A fuel battery comprises a unit cell(10) which includes an electrolyte membrane(11), an air electrode(12) formed in one side of the electrolyte film and a fuel anode(13) formed in the other side of the electrolyte film, an air electrode current collector(14) which is located in the outside of the air electrode, a first separator(31) which is located in the outside of the air electrode collector, and a first bonding element(51) which welds the air electrode collector and the first separation board. Separation protrusion parts(31a) and separation depression parts(31b) are formed on surface of the first separation board by turns. |
