    摘要： This invention provides an assembly comprising a sensing electrode and a counter electrode in contact with a membrane body formed from a solid polymer electrolyte system comprising a fluorinated polymer matrix and a charge carrying component which is dispersed in the matrix the electrodes and membrane being housed in a housing having a gas diffusion barrier through which gas may flow. The charge carrying components are fluorinated organic proton conductors (such as heptadecafluorooctane sulphonic acid, bis-trifluoromethane sulphonamide, N-(2,6-diethylphenyl)-1,1,1-trifluoromethane sulphonamide, N-benzyltrifluoromethane sulphonamide and N, N-1,2-cyclohexanediylbis (1,1,1-trifluoromethane sulphonamide)). The polymer matrix is a homopolymer or copolymer of vinylidene fluoride preferably with fluorinated comonomers. The solid polymer electrolyte system preferably contains plasticising additive(s) and is cast as a coating onto one or more electrodes eg. Platinum gas diffusion electrodes forming an assembly for use in a gas sensor especially a CO sensor.

    摘要： A polymer electrolyte comprises a polymer combined with a solution of a salt in a plasticising solvent, and the polymer is a terpolymer of vinylidene fluoride (VdF), hexafluoropropylene (HFP), and chlorotrifluoroethylene (CTFE). The proportion by weight of vinylidene fluoride is at least 85 %. The polymer has a large enough molecular weight that its melt flow index, at 230 DEG C and 21.6 kg, is less than 5.0 g/10 min. The resulting polymer electrolyte may be referred to as a solid electrolyte or a gelled electrolyte, and is suitable for use as the separator/electrolyte in an electrochemical cell, such as a secondary lithium ion cell.
