Abstract: A method of recovering waste water from hydrocarbon production wells includes filtering contaminated water directly from a production site and filtering through a perfluorosulfonic acid containing membrane to produce purified steam while losing only about 1 atmosphere of pressure. The steam can be used for energy recovery or condensed and recycled into a subsequent production site.

Abstract: Systems and processes for producing hydrogen using bacteria are described. One detailed process for producing hydrogen uses a system for producing hydrogen as described herein, the system including a reactor. Anodophilic bacteria are disposed within the interior of the reactor and an organic material oxidizable by an oxidizing activity of the anodophilic bacteria is introduced and incubated under oxidizing reactions conditions such that electrons are produced and transferred to the anode. A power source is activated to increase a potential between the anode and the cathode, such that electrons and protons combine to produce hydrogen gas. In one system for producing hydrogen is provided which includes a reaction chamber having a wall defining an interior of the reactor and an exterior of the reaction chamber.

One system for producing hydrogen includes a reaction chamber having a wall defining an interior of the reactor and an exterior of the reaction chamber. An anode is provided which is at least partially contained within the interior of the reaction chamber and a cathode is also provided which is at least partially contained within the interior of the reaction chamber.

Abstract: A method for recovering and recycling catalyst coated fuel cell membranes includes dissolving the used membranes in water and solvent, heating the dissolved membranes under pressure and separating the components. Active membranes are produced from the recycled materials.

Abstract: Electrodes coated with transport polymer such as perfluoroether aid in water management and CO mitigation in fuel cells.

Abstract: A perfluorinated ion exchange membrane useful for membrane electrode assemblies and fuel cells and having improved ionic conductivity and water absorption characteristics.

Abstract: A method of manufacturing fuel cell membrane electrode assemblies using solution cast films, and the resulting electrode assemblies. The assemblies are prepared by applying a catalyst slurry onto a decal, subsequently applying ionomer solution and at least partially curing the ionomer.
