This invention describes a low-cost, lightweight, high-performance composite bipolar plate for fuel cell applications. The composite bipolar plate can be produced using stamped or pressed into the final form including flow channels and other structures prior to curing.

Low-cost, high-performance composite bipolar plate

The present method includes graphene, preferably in the form of flat graphene oxide flakes with, by mass, preferably between 0.5% and 35% PAN. The graphene oxide and conductive-polymer PAN is in a co-suspension in water and is co-deposited on a surface. The deposited PAN with a high-percentage graphene-oxide layer is dried. Our tests have produced electrical conductivities 1000 times more conductive than the PAN by itself. Our testing indicates that using flakes that are flat is essential to getting very high conductivity, and that controlled oxidation is very important in suspending graphene oxide in water.

Graphite oxide and polyacrylonitrile based composite

This can be a method of making a high strength composite reinforcing fiber using flat GO flakes coated on a conventional reinforcing fiber. This maintains some the flexibility of the fiber and aligns the flat graphene flakes along the surface of the fiber; this dramatically increases the strength of the fiber. It also allows bonding between overlapping flakes, in contrast to flakes being uniformly dispersed in a host material that is being reinforced and dramatically increases the strength of the host material.

Graphite oxide reinforced fiber in hosts such as concrete or asphalt

This is generally a method of producing dispersed high quality engineered composite structures using flat flakes of graphene/graphene oxides/reduced graphene oxides in a host as the reinforcing additive of the composite.

Engineered composite structure using graphene oxide

A method of producing dispersed of high quality graphene/graphite oxides in a powder matrix to then be reacted to form a composite. Where the powders have similar hydrophobicity and the graphene/graphite oxides has minimal surface oxidation or minimal epoxy group and where the powders are sonically mixed.

In one general aspect, a sample area is energized. A thermal energy status of the sample area is monitored. The thermal energy status including at least one of a radiant energy and a temperature. A thermal signature of a region included in the sample area is determined based on the thermal energy status of the region. The thermal signature is analyzed to determine whether explosive particles are included in the region.

Energetic material detector

A method of detecting energetic materials, such as explosives, includes energizing a sample area that contains particles of energetic materials. In the method, temperature characteristics from the sample area are monitored, and a temperature released from exothermic decomposition of the particles is detected. The method further includes analyzing the detected temperature to determine the presence of the exothermic compound which caused the decomposition.
