NOVELTY - Fixture for a fuel cell, which supports a membrane and electrode assembly (MEA), comprises a passage for fuel gas-water, a passage wall for supporting passage and acting as gasket for preventing leakage, and coupling hole for inserting a rod for coupling MEA and fixture. Passage wall has a height lower than that of an inner surface of fixture. The passage and passage wall are arranged in parallel.    USE - The fixture is used for supplying fuel gas to proton exchange membrane fuel cell (PEMFC), for portable electronic equipment.    ADVANTAGE - The fixture has high heat conductivity to maintain stability in oxidation and reduction reactions and efficiently discharge heat generated due to the reduction reaction. The fixture has high electrical conductivity to smoothly transport electron generated on anode side to cathode side. The fixture simplifies manufacturing process, by eliminating precision processes, using a material that has less property variation when contacted with water and sufficient flexibility permitting a passage to transport supplied gas. The fixture is strong enough to resist external impact and needs no separate gasket for preventing fuel gas or generated water leakage.    DETAILED DESCRIPTION - A fixture for proton exchange membrane fuel cell which supports a membrane and electrode assembly (MEA) comprises an inlet (210) for fuel gas, a supply hole (230) for transporting the gas, a passage (300) for fuel gas and generated water, a passage wall (310) for supporting the passage and acting as a gasket for preventing leakage from passage, an outlet (260) for discharging residual gas and liquid generated, and a coupling hole (400) for inserting a rod for coupling MEA and fixture during coupling the unit cell. The passage wall has a height lower than that of an inner surface of fixture, and the passage and the passage wall are arranged in parallel to each other for the gas/liquid to be simultaneously transported along two passages.
