摘要： An object of the present invention is to provide an electrolyte membrane that suppresses swelling and shrinkage caused by water retained in the electrolyte membrane for a solid polymer-type fuel cell, improves the durability of the electrolyte membrane, and obtains excellent power generation characteristics with a low resistance. The electrolyte membrane for a solid polymer-type fuel cell includes, as a reinforcing membrane, a nonwoven fabric composed of an electrolyte material and PVDF bicomponent fibers 2a, thereby improving the durability of the electrolyte membrane. Furthermore, the bicomponent fiber 2a has pores 23 that can effectively retain generated water, thereby improving battery performance under the condition of a low humidity.

摘要： The invention relates to very high melt flow fluoropolymer compositions, having low melt viscosities. The fluoropolymers have low molecular weights of from 5 kDa to 200 kDa and melt viscosities of less than 2 kilopoise (kP) at 232° C. and 100 s−1. One use for the high melt flow fluoropolymers is in the formation of very small diameters fibers, useful for melt-blown non-woven materials. Fiber diameters of less than 9 microns, and preferably 500 to 2000 nm can be produced.

摘要： An improved process for forming a PTFE mat is described. The process includes providing a dispersion with PTFE, a fiberizing polymer and a solvent wherein said dispersion has a viscosity of at least 50,000 cP. An apparatus is provided which comprises a charge source and a target a distance from the charge source. A voltage source is provided which creates a first charge at the charge source and an opposing charge at the target. The dispersion is electrostatically charged by contact with the charge source. The electrostatically charged dispersion is collected on the target to form a mat precursor which is heated to remove the solvent and the fiberizing polymer thereby forming the PTFE mat.
