ELASTOMERIC CELL FRAME FOR FUEL CELL, MANUFACTURING METHOD OF THE SAME AND UNIT CELL USING THE SAME

An elastomeric cell frame for a fuel cell includes an insert which includes: a membrane electrode assembly including a polymer electrolyte membrane and a pair of electrode layers respectively disposed on opposite sides of the polymer electrolyte membrane; and a pair of gas diffusion layers disposed and bonded on upper and lower surfaces of the membrane electrode assembly, respectively. The insert further includes an elastomeric frame disposed in an external region of the insert. The elastomeric frame surrounds one of opposite edge surfaces of the insert and a side surface of the insert, the elastomeric frame being interface-bonded, through thermal bonding, to portions of the polymer electrolyte membrane and the electrode layers exposed at the one of opposite edge surfaces of the insert and the side surface of the insert.
