Abstract: A metal-supported porous carbon film wherein metal fine particles with a mean particle diameter of 0.7-20 nm are dispersed and supported on pore surface walls, fuel cell electrodes employing the metal-supported porous carbon film, a membrane-electrode assembly comprising the fuel cell electrodes bonded on both sides of a polymer electrolyte film, and a fuel cell comprising the fuel cell electrode as a constituent element. The support structure is such that metal fine particles having a controlled particle size are uniformly supported to allow effective utilization of the metal-based catalyst, and the fabrication steps are simple.

Abstract: The present invention pertains to a porous polyimide film production method and a porous polyimide film produced using said method, said method including: a step (1) in which a polyamic acid solution comprising 40%-97% by mass organic polar solvent and 3%-60% by mass polyamic acid having an intrinsic viscosity, comprising tetracarboxylic acid units and diamine units, of 1.0-3.0 is cast in film form and immersed in or caused to come in contact with a coagulating solvent having water as an essential component thereof, and a porous film of polyamic acid is produced; and a step (2) in which the porous film of polyamic acid obtained in said step is heat treated and imidized. Shrinkage in the film longitudinal direction and transverse direction after heat treatment is suppressed to no more than 8% for each direction and the speed of temperature increase in a temperature range of at least 200°C during the heat treatment is at least 25°C/min.

Abstract: A lower alcohol compound is separated from a mixture of a lower alcohol compound and an ether compound by a pervaporation method comprising the steps of: bringing a feed comprising an ether compound and a lower alcohol compound into direct contact with a feed face of a specific asymmetric separating membrane comprising an aromatic imide polymer which has 70 to 100 molar% of recurring units selected from those of the formulae (I) and (II) (I) and (II) wherein R = divalent aromatic group having two or more benzene rings and X = -S-, -SO2-, -CO-, -O-, -C(CH3)2-, -CH2- and -C(CF3)2-; exposing a delivery face Opposite to the feed face of the membrane to a pressure-reduced atmosphere to cause the lower alcohol compound to selectively permeate through the membrane and to be then vaporized at the delivery face side, and collecting the lower alcohol compound at the delivery face side of the membrane.
