NOVELTY - The membrane electrode structure (1a) has pair of electrodes (7,8) provided with catalyst layer (3,4) and solid polymer electrolyte membrane (2) provided between catalyst layers of electrodes. At least one surface of the membrane (2) is covered with a catalyst layer, and an adhesive support layer (9) provided around the peripheral side of the catalyst layer adheres to the membrane (2) and supports the membrane (2).    USE - For solid polymer fuel cell and apparatus for transport (claimed). The polymer fuel cell is used for power supply of electric equipment, personal computer, mobile telephone, backup power supply, and for apparatus for transport such as ships, motor vehicle and submarine.    ADVANTAGE - The adhesive support layer has roughness and does not peel even when exposed at high temperature and high humidity during fuel battery running. The support layer protects solid polymer electrolyte membrane extended from the periphery of the catalyst layer to outside film and the damage is prevented. Plastic deformation and damage on the porous diffused layer are suppressed and the plastic deformation amount with respect to the load with reduced.    DETAILED DESCRIPTION - The membrane electrode structure has pair of electrodes provided with a catalyst layer and solid polymer electrolyte membrane provided between catalyst layers of the electrodes. A catalyst layer is positioned at an inner circumference side rare than the periphery edge of the solid polymer electrolyte membrane. At least one surface of the solid polymer electrolyte membrane is covered with a catalyst layer, and an adhesive support layer provided around the peripheral side of the catalyst layer adheres to the solid polymer electrolyte membrane and supports the solid polymer electrolyte membrane. The adhesive support layer consists of an adhesive agent having a fluorine atom in a molecular structure. The adhesive agent contains a polysiloxane compound and molecule having at least two alkenyl group.    INDEPENDENT CLAIMS are included for the following:    (1) solid polymer fuel cell;    (2) apparatus for transport; and    (3) manufacture of membrane electrode structure.
