A proton exchange membrane which includes a sulfonated and phosphonated poly (styrene) material having a covalently bonded tertiary hydrogen replacement group.

High stability membrane for proton exchange membrane fuel cells

An apparatus for generating electricity having an anode electrode, a cathode electrode and a proton exchange membrane comprising poly(vinyl alcohol) disposed between the anode electrode and the cathode electrode. The proton exchange membrane of this invention is suitable for operating at a temperature over an entire range of about room temperature to about 170&#xb0; C. In accordance with preferred embodiments, the membrane includes one or more cross-linking agents.

High temperature composite proton exchange membranes

Coated particles made of particulate substrates having a coating of resin and fibrous material are provided for use in subterranean formations. The coated substrate particles are proppants useful to prop open subterranean formation fractures. The coated substrate particles are also useful for sand control, that is, acting as a filter or screen to prevent backwards flow of sand, other proppants or subterranean formation particles. Methods of making the coated particles are also disclosed.
