An electrical energy generating device which is able to supply oxygen in atmospheric air efficiently to an oxygen electrode and to vaporize water yielded off efficiently, and which has superior waterproof characteristic. The device includes a number of cells each having a hydrogen electrode plate, a proton conductor film and an oxygen electrode plate, and a sheet coverwhich is air-permeable and waterproofed and which shrouds each cell.

Electric energy generating element

Methods and devices for producing fullerene are provided. The present invention includes a pair of electrodes spaced apart to define a region wherein an arc discharge can be conducted between the electrode pair and a gas containing carbon can be supplied to the region such that fullerene can be easily and readily produced.

Method and system for production fullerene

An arc electrode structure, for producing carbon nanostructures, which includes a first electrode and two or more second electrodes disposed within a chamber is provided. The electrodes are connected to a voltage potential to produce an arc-plasma region. The first electrode has a sloped surface with a plurality of holes therein for holding catalyst. The first electrode's sloped surface, and the positioning of the plurality of second electrodes allows control of the direction and region of arc-plasma. Further, the first electrode has a central bore which may be either a blind bore, or a through bore. The blind bore collects unwanted deposits that slide off of the sloped surface of the first electrode. The throughbore either allows soot and carbon nanostructures to be removed from the chamber, or allows organic vapor to be introduced into the chamber. When the throughbore is used to introduce organic vapor into the chamber, the vapor is directed through the arc-plasma region so that carbon nanostructures are built up by a CVD process rather than being broken off of carbon electrodes.

Arc electrodes for synthesis of carbon nanostructures

An apparatus and method for manufacturing a carbonaceous material are provided. The carbonaceous material manufacturing apparatus includes a reaction tube and a gas supply portion. An anode and a cathode defining an arc discharge portion is placed in the reaction tube, and a capturer is located provided as well to capture carbonaceous materials generated. At the location of the capturer, an RF heater is disposed around the reaction tube. In a carbonaceous material manufacturing method, carbonaceous materials generated in the arc discharge portion are transported from a gas supply portion into the reaction tube by the gas supplied into the reaction tube, then heated by a RF heater in the capturer where the carbonaceous materials are not exposed to the atmospheric air, to thereby promote removal of impurities and growth of single-walled carbon nanotubes.
