A protective coating for a surface comprising a layer permeable to hydrogen, said coating being deposited on a catalyst layer; wherein the catalytic activity of the catalyst layer is preserved.
This invention provides a novel battery structure that, in some variations, utilizes a mixed lithium-ion and electron conductor as part of the separator. This layer is non-porous, conducting only lithium ions during operation, and may be structurally free-standing. Alternatively, the layer can be used as a battery electrode in a lithium-ion battery, wherein on the side not exposed to battery electrolyte, a chemical compound is used to regenerate the discharged electrode. This battery structure overcomes critical shortcomings of current lithium-sulfur, lithium-air, and lithium-ion batteries.

Abstract:
A process of one embodiment of the invention includes providing a fuel cell bipolar plate comprising carbon exposed at an outer surface of the bipolar plate and reacting a diazonium salt with the exposed carbon so that a functional group is attached to the exposed carbon to increase the hydrophilicity of the bipolar plate where the functional group is attached.
Modified Carbon Material And Process Of Making And Using The Same
A method of making modified carbon materials for use in fabricating fuel cell components. The modified carbon may comprise pendant fluorocarbon groups bonded covalently bonded thereto. In one embodiment, a mixture is formed and comprises carbon material suitable for use in a fuel cell component, an organic solvent, a compound having the general formula I-R wherein R is a fluorocarbon, and a reductant.
Battery With Reference Electrode For Voltage Monitoring
A lithium-ion battery structure with a third electrode as reference electrode is disclosed. The reference electrode may be fabricated from lithium metal, lithiated carbon, or a variety of other lithium-containing electrode materials. A porous current collector allows permeation of reference lithium ions from the reference electrode to the cathode or anode, enabling voltage monitoring under actual operation of a lithium-ion battery. The reference electrode therefore does not need to be spatially between the battery anode and cathode, thus avoiding a shielding effect. The battery structure includes an external reference circuit to dynamically display the anode and cathode voltage. The battery structure can result in improved battery monitoring, enhanced battery safety, and extended battery life.

International Classification:
H01M 8/02
US Classification:
427115
Abstract:
The present invention provides methods for fabricating a fuel cell membrane structure that can dramatically reduce fuel crossover, thereby improving fuel cell efficiency and power output. Preferred composite membrane structures include an inorganic layer situated between the anode layer and the proton-exchange membrane. The inorganic layer can conduct protons in unhydrated form, rather than as hydronium ions, which reduces fuel crossover. Some methods of this invention include certain coating steps to effectively deposit an inorganic layer on an organic proton-exchange membrane.
