Abstract: A fuel cell module comprises: at least one cell stack including a plurality of single fuel cells supplied with a fuel gas and an oxidizing gas to generate power; a sealable housing accommodating the at least one cell stack and forming a power generation chamber inside the housing; a pressure vessel accommodating the housing; and an oxidizing gas supply pipe for supplying the oxidizing gas to the cell stack. At least one pressure equalizing opening is formed in the housing to allow communication between inside and outside of the housing. The at least one pressure equalizing opening includes only one pressure equalizing opening, or a plurality of pressure equalizing openings in which a distance between a pressure equalizing opening in the highest position and a pressure equalizing opening in the lowest position is within 0.1H, where H is a height of the housing.

Abstract: An object of the present invention is to provide a nonwoven fabric having high tensile strength and high tear strength. The laminate nonwoven fabric of the present invention is a laminated nonwoven fabric obtained by thermally press-contacting a thermoplastic continuous fiber layer as an outer layer with both surfaces of an interlayer, wherein the ratio (F1/F2) between the average oblateness (F1) of the thermoplastic continuous fiber present on the surface side and the average oblateness (F2) of the thermoplastic continuous fiber present on the inner side is 1.20 or more.

Abstract: An object of the present invention is to provide a composite membrane support composed of a dry process thermoplastic resin filaments nonwoven fabric having a significantly high uniformity to enable formation of a porous layer free from strike-through or a defect such as pinhole at the film formation, producing no skin layer defect at the formation of a skin layer, and being excellent in the mechanical strength and dimensional stability at high temperatures, and a high-performance composite membrane and a composite membrane element each using the composite membrane support. The composite membrane support of the present invention is a laminate dry process thermoplastic resin filaments nonwoven fabric comprising three or more layers containing at least a meltblown fiber layer as an interlayer and spunbond fiber layers on both sides of the interlayer, wherein the average value of air flow resistance is from 2.0 to 30.
