H01M 4/90
H01M 4/86

Abstract:

A composition used to form the active layer of a solar cell or hydrogen fuel cell that comprises, consists of or consists essentially of a homogenous dispersion, poly(3-hexylthiophene-2,5-diyl) (P3HT) and 1-(3-methoxycarbonyl)propyl-1-phenyl[6,6]C(PCBM). The homogenous dispersion comprises, consists of or consists essentially of graphene oxide (GO) or reduced graphene oxide (RGO) and sulfonated polystyrene (PSS) or para-methoxy-N-methylamphetamine (PMMA). The GO or RGO can be functionalized with a metal, preferably gold (Au), platinum (Pt), palladium (Pd) or ferric oxide (FeO).

H02J 50/80
H02J 50/10

Abstract:

A wireless electrical charging system includes a wireless communication unit that may emit a radio frequency signal. An induction unit is electrically coupled to a power source. The induction unit is in electrical communication with the wireless communication unit. The induction unit may communicate an electrical signal to the wireless communication unit. Thus, the radio frequency signal may carry the electrical signal. A receiving unit is in electrical communication with the wireless communication unit. Thus, the receiving unit may receive the electrical signal from the wireless communication unit. The receiving unit may be selectively electrically coupled to an extrinsic electronic device. Thus, the receiving unit may charge the extrinsic electronic device.

Abstract:

A polymer electrolyte membrane fuel cell that includes a positive electrode, a negative electrode, a polyelectrolyte membrane and a solution of reduced graphene oxide and/or graphene oxide functionalized with metallized nanoparticles. The electrodes are coated with a polymer and the polyelectrolyte membrane has a hydrophobic exterior surface that is subjected to ultraviolet/ozone (UV/O) exposure, which changes the hydrophobic, exterior surface to a hydrophilic exterior surface. The polyelectrolyte membrane is disposed between the positive electrode and the negative electrode and can include a sulfonated tetrafluoroethylene based fluoropolymer-copolymer. The solution forms a coating on the hydrophilic exterior surface of the polymer electrolyte membrane and the positive and negative electrodes. The positive and negative electrodes can be coated with a polymer, preferably polytetrafluoroethylene (PTFE) that can be subjected to ultraviolet/ozone (UV/O) exposure. The metallized nanoparticles increase the efficiency of the fuel cell by at least 50% when the feed gas includes at least 1000 ppm carbon monoxide.

US Classification:

Abstract:

A method of attaching reduced graphene oxide and/or graphene oxide to a polymer layer that includes: forming a polymer layer having a hydrophobic, exterior surface; subjecting the hydrophobic, exterior surface of the polymer layer to ultraviolet/ozone (UV/O) exposure to change the hydrophobic, exterior surface to a hydrophilic, exterior surface; and applying reduced graphene oxide and/or graphene oxide to the hydrophilic surface of the polymer layer. The UV/Oexposure reduces the contact angle of droplets on the exterior surface of the polymer layer so that greater amounts of reduced graphene oxide and/or graphene oxide can be applied to the surface.
