A solid electrolyte film including a resin having a repeating unit containing a bis(perfluoroalkanesulfonyl)methide moiety. This solid electrolyte film combines high proton conductivity with low methanol permeability for prevention of methanol crossover and can suitably be used for a direct methanol fuel cell.
摘要:
A solid electrolyte film according to the present invention includes a resin having a repeating unit of the general formula (1) containing a bis(perfluoroalkanesulfonyl)methide moiety: where R represents a hydrogen atom or a methyl group; Y represents an oxygen atom or NH; Rf represents a C1-C4 perfluoroalkyl group; and W represents either a C2-C4 straight or C3-C4 branched alkylene group or a C5-C8 cyclic hydrocarbon group as a linking group, which may have a branched chain or a cross-linking structure.This solid electrolyte film combines high proton conductivity with low methanol permeability for prevention of methanol crossover and can suitably be used for a direct methanol fuel cell etc.
摘要:
Disclosed are a solid electrolyte membrane for fuel cells, which is characterized by that there has been used a silicone resin obtained by subjecting a methide series siloxane compound having a specific, strong acid bis(perfluoroalkanesulfonyl)methide moiety, a specific polysiloxane compound, and a specific silane compound to a cross-linking reaction, and its production process. This membrane has heat resistance, is superior in chemical stability, has a good proton conductivity even under a low water content condition, and has a low methanol permeability.

Disclosed is a proton conducting polymer membrane formed by laminating a plurality of solid electrolyte membranes. This proton conducting polymer membrane is one prepared by laminating at least one layer of a solid electrolyte membrane formed by using a resin having a bis(perfluoroalkanesulfonyl)methide group in the chemical structure. This solid electrolyte membrane has a superior proton conductivity without transmitting the fuel (methanol or hydrogen).
摘要:
[Problem] To provide an antibacterial agent which can be limited to the required location on the surface of a material without mixing and has excellent antibacterial, antifungal and antiviral effects even at low concentrations of the active component without elution or volatilization.[Solution] An antibacterial agent that contains as an active component a resin having an organic group represented by general formula (I-1). (In the formula (I-1), R1 and R2 mutually independently represent a C1-C4 fluoroalkyl group. “C” and “A” are bonded to each other through a covalent bond or an ionic bond, and “A” represents a hydrogen atom or a cation.)

摘要:
The present invention relates to novel first to fourth lactone compounds. The first lactone compound is represented by the formula (1), in the formula, X represents CH2, CH2CH2, O, S or NR1, and R1 represents hydrogen atom, a straight-chain, branched or cyclic alkyl group of a carbon number of 1–10. Hydrogen(s) of the alkyl group may partially or entirely be replaced with fluorine atom(s). Furthermore, a part of the alkyl group may contain an atomic group containing oxygen atom, sulfur atom, nitrogen atom, carbon-carbon double bond, carbonyl group, hydroxy group or carboxyl group.
