An apparatus for producing a porous body that forms an expandable slurry containing at least inorganic powder, a foaming agent, and a binder into a sheet, causes the expandable slurry sheet to be foamed and baked, and thereby produces the porous body, the apparatus includes: a mixer preparing the expandable slurry by containing inorganic powder, a foaming agent, and a binder; a die-coater that has a discharge opening which discharges the expandable slurry provided from the mixer to an external thereof so as to shape the expandable slurry into a sheet; and a carrier sheet arranged so as to face the discharge opening of the die-coater with a gap interposed therebetween, and feeding the expandable slurry discharged from the discharge opening, wherein a flow path of the expandable slurry from inside the mixer to the discharge opening of the die-coater is hermetically sealed from an outside.

Apparatus for producing porous body and method for producing porous body

A composite porous body, a gas diffusion layer member of a polymer electrolyte fuel cell, a cell member for the polymer electrolyte fuel cell, and manufacturing methods thereof are provided. The composite porous body is a metallic composite porous body in which a sheet-like metal portion composed of a composite porous body having a three-dimensional mesh structure and a resin portion extending in an in-plane direction of the metal portion are integrally formed with each other. The gas diffusion layer member of a polymer electrolyte fuel cell is composed of a composite porous body in which a sheet-like metal portion composed of a composite porous body having a three-dimensional mesh structure and a resin portion extending in an in-plane direction of the metal portion are integrally formed with each other. Also, the gas diffusion layer member of a polymer electrolyte fuel cell has a separator plate, and the conductive porous body placed on at least one surface of the separator plate. A resin frame is integrally provided so as to cover the peripheries of separator plate and the conductive porous body.
