Provided is a method for forming a good fibrous coating on a target surface even in a high-humidity environment when electrostatically spraying is performed directly on the target surface such as skin. A composition for forming a coating of fibers on a target object by electrostatic spraying, comprising the following components (a), (b), (c) and (d):

Composition for forming coating

A multilayer nanofiber sheet () includes: a nanofiber layer () including nanofibers which comprise a water-soluble polymer compound; a substrate layer () arranged on one surface side of the nanofiber layer (); and a water-insoluble porous layer () arranged on the other surface side of the nanofiber layer (). The three layers are layered, and the multilayer nanofiber sheet is used in a state in which a surface thereof on the porous layer side is arranged so as to face a surface of an object. Preferably, the three layers are layered in a fixed state. Preferably, the porous layer () has a thickness of from 3 to 1000 &#x3bc;m.

Multilayer nanofiber sheet and adhesion method for same

A method and apparatus for manufacturing a membrane electrode assembly are provided, which can efficiently peel an electrode layer from a base material. A manufacturing apparatus for manufacturing a membrane electrode assembly of a fuel cell including a pair of electrode layers and an electrolyte membrane, the apparatus including: a transport device which transports the base material on which one cathode electrode layer of the pair of electrode layers is formed and which is connected to a transport sheet via an adhesive layer together with the transport sheet; a transfer device which transfers the one cathode electrode layer to the electrolyte membrane; a peeling device which peels the cathode electrode layer from the base material; and a cooling device having a spraying device which is directed to a start point portion for the peeling and sprays a cooling gas.

Method and apparatus for manufacturing membrane electrode assembly

In a membrane electrode assembly, electrode catalyst layers are provided respectively on both surfaces of an electrolyte membrane. Each of the electrode catalyst layers includes polymer electrolyte and catalyst. In each of the electrode catalyst layers, the weight of a component of the polymer electrolyte contained in one surface facing the electrolyte membrane is twice as large as, or more than twice as large as the weight of the component of the polymer electrolyte contained in another surface.
