This disclosure is about invention of fuel cells comprising vertically free-standing graphene-containing carbon nanosheets in the components, and methods of making thereof. Performance enhancement effect of the fuel cell is achieved by using vertically free-standing graphene-containing carbon nanosheets as: 1) surface coating of electrically conducting components, 2) and/or a geometric geometric structural supporter of additive catalyst materials, 3) and/or a synergic catalytic nano-composite

Fuel cells using vertically free standing graphene and carbon nanosheets

Aspects of the invention are directed to a method for forming a hybrid structure. Initially, a wire is received and an encapsulating film is deposited on the wire. Subsequently, the wire is selectively removed to leave a hollow tube formed of the encapsulating film. A plurality of active particles are then placed into the hollow tube by immersing the hollow tube in a suspension comprising the plurality of active particles and a liquid. Lastly, the hollow tube and the plurality of active particles therein are removed from the suspension and allowed to dry so as to form a cluster of active particles at least partially encapsulated by the encapsulating film.

Graphene hybrid structures for energy storage applications

Aspects of the invention are directed to a method of forming graphene structures. Initially, a cluster of particles is received. The cluster of particles comprises a plurality of particles with each particle in the plurality of particles contacting one or more other particles in the plurality of particles. Subsequently, one or more layers are deposited on the cluster of particles with the one or more layers comprising graphene. The plurality of particles are then etched away without substantially etching the deposited one or more layers. Lastly, the remaining one or more layers are dried. The resultant graphene structures are particularly resistant to the negative effects of aggregation and compaction.

Graphene structures with enhanced stability and composite materials formed therefrom

Aspects of the invention are directed to a method for forming a graphene composite structure. Initially, an encapsulating film is formed on a substrate. The encapsulating film comprises graphene. Subsequently, a plurality of particles are deposited on the encapsulating film, and then a temporary layer is deposited on the plurality of active particles and the encapsulating film. The substrate is then removed. Lastly, the temporary layer is also removed so as to cause the plurality of particles to form a cluster that is at least partially encapsulated by the encapsulating film.

Graphene composite electrodes for energy storage devices

An arrangement for discharge of electricity or lightning in the atmosphere to prevent formation of space charges that would reduce the strength of electric fields therein by transmitting through a path in the atmosphere one or more first leaser pulses of wavelength essentially within the ultraviolet range and of duration sufficient to create an electrically conductive ionized channel in the atmosphere and simultaneously transmit in said path one or more second laser pulses of longer wavelength than the ultraviolet pulses to maintain the conductivity of the channel for a time long enough for lightning to occur therein.
