Abstract
A fuel cell is disclosed. The fuel cell can include a membrane electrode assembly (MEA), converting a chemical energy to an electrical energy; a first end plate, stacked on one surface of the MEA and formed with a first coupling hole; a second end plate, stacked on the other surface of the MEA; and a protrusion, formed on the second end plate such that the protrusion penetrates the first coupling hole and an end part of the protrusion protrudes a surface of the first end plate, and the end part being transformed such that the end part couples the first end plate and the second end plate. With the present invention, the fuel cell can reduce contact resistance between elements and its overall size and prevent a leak of fuel. In the manufacturing process, the end plates and the MEA can be arranged, improving reproducibility and repetition for mass production.
