摘要： A porous supporting carbon body of a gas diffusion layer is provided with a larger number of smaller pores at its catalyst layer side and a smaller number of larger pores at the other side, particularly with an appropriate distribution of finer mesh at its catalyst layer side and coarser mesh at the other side. As a result, a high performance polymer electrolyte fuel cell is obtained in which water generated at the catalyst layer is quickly sucked out to the gas diffusion layer, and is evaporated at the gas diffusion layer to be effectively exhausted to outside the fuel cell, so that excessive water can be prevented from retaining in the gas diffusion electrode, with the polymer electrolyte membrane being maintained at an appropriately wet condition.

摘要： A method for forming a molecular film includes the steps of: coating a surface of a substrate having active hydrogen atoms on its surface with a coating solution containing a silane-based compound having at least one reactive group selected from the group consisting of a chloro group, an alkoxy group and an isocyanate group; and effecting an elimination reaction between the active hydrogen atoms on the surface of the substrate and reactive groups of the silane-based compound, thereby covalently bonding the silane-based compounds to the surface of the substrate. The substrate is supplied to a chamber in which an atmosphere is maintained at a low water vapor density. The surface of the substrate is coated with a coating solution containing the silane-based compound and a solvent by using a transfer element. A dehydrochlorination reaction is effected between the active hydrogen atoms and the chloro groups of the silane-based compounds. Thereafter, any coating solution containing unreacted silane-based compounds after coating is removed inside or outside the chamber.

摘要： A method for manufacturing a chemically bonding material comprising the steps of: mixing a compound expressed by a general formula ABX.sub.n (Formula 1), wherein A shows a group including carbon, B indicates Si, Ge, Sn, Ti or Zr, X is a hydrolyzable group and n indicates 1, 2 or 3, and at least one kind of compound not including active hydrogen groups in a dry atmosphere having a water vapor density of 0.0076 kg/m.sup.3 or less; and storing the same in a dry atmosphere having a water vapor density of 0.0076 kg/m.sup.3 or less. A coating solution including compounds that are easily hydrolyzed is stored in a dry state so that the material is not deactivated before reacting with a substrate.
