A fuel cell comprises a membrane electrode assembly configured such that electrode catalyst layers are formed on respective surfaces of an electrolyte membrane; gas diffusion layers placed on respective surfaces of the membrane electrode assembly; and a frame placed around periphery of the membrane electrode assembly. The membrane electrode assembly has a protruding portion that is configured by protruding outside of the gas diffusion layer in a state that the membrane electrode assembly is combined with the gas diffusion layers. The frame has an engagement portion that is configured to engage with the protruding portion. An adhesive layer is formed from an ultraviolet curable adhesive between the protruding portion and the engagement portion.

Fuel cell and method of manufacturing fuel cell

A fuel evaporative-gas emission preventing apparatus capable of reducing the quantity of adsorption of a canister as low as possible by a single breather at any fueling speeds and allowing emissions to fall within given limits. One end of the breather is coupled to a portion near a port of an inlet pipe for a fuel tank and a differential pressure regulating valve is connected to the other end of the breather. The canister is coupled to the differential pressure regulating valve. An opening-area variable device is provided at an intermediate portion of the breather and adjusts the quantity of a fuel evaporative-gas in the breather according to an internal pressure of the fuel tank.
