摘要： A thin film composed of a silane-based compound comprising an alkyl group or a fluoroalkyl group is bonded to the surface of an electrically insulating substrate through a covalent bond, thus obtaining an electrically chargeable substrate maintaining a charged state for a long time regardless of relative humidity of an atmosphere. A glass plate for placing a sheet in an overhead projector is dipped into a solution comprising CF3(CF)7(CH2)2SiCl3. As a result, a molecular composed of CF3(CF2)7(CH2)2Si(O)3—is chemically bonded to the glass surface.

摘要： By forming a film that comprises a microcrystalline polymer having at least a fluorocarbon group and has a rough surface on a surface of a base material, super-water-repellency is provided, the dew condensation water of an air conditioner, for example, can be easily removed, and the freezing of the fin of the heat exchanger can be prevented. A fin that is made of aluminium is coated with a solution for forming a coating film, in which CF.sub.3 (CF.sub.2).sub.7 --(CH.sub.2).sub.2 --SiCl.sub.3 is diluted with nonaqueous cyclohexamethyl trisiloxane at a concentration of 10 vol. % for preparation, to a thickness of 1 to 10 .mu.m by a brush, and then the cyclohexamethyl trisiloxane is vaporized in an atmosphere having a relative humidity of about 75% at room temperature. CF.sub.3 (CF.sub.2).sub.7 --(CH.sub.2).sub.2 --SiCl.sub.3 that remained on the fin is rapidly hydrolyzed with the moisture in the atmosphere, and the moisture in air and a --SiCl.sub.3 group dehydrochlorinated to form a microcrystalline polymer on the fin. As a result, a coating film having a surface roughness in the range of 1 to 40 .mu.m and a contact angle of about 171.degree. to water can be formed.

A reaction gas passage region (101) of a separator (2) has a flow splitting region (21) having a passage groove group where the reaction gas is split, and one or more flow merge regions (22) having a recessed portion in which the reaction gas is mixed and connecting a plurality of flow splitting regions so that the passage groove group of the adjacent flow splitting regions (21) are connected to the recessed portion, and protrusions (27) vertically extend from a bottom face of the recessed portion and arranged in an island form. A pair of passage groove groups connected to the recessed portion of the flow merge region (22) is formed so as to have a greater number of grooves in the upstream passage groove group than the number of grooves of grooves in the downstream passage groove group. The recessed portion of the flow merge region (22) is defined, in a turn portion of a serpentine shaped reaction gas passage region (101), by oblique boundaries between the recessed portion and a pair of passage groove groups which are connected to the recessed portion and by the outer end of the turn portion.

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.
