摘要:
A liquid fuel for a fuel cell comprises an organic compound and at least one kind of anti foaming agent. A catalyst electrode is capable of, when used for a fuel cell, increasing in an effective surface area of a fuel electrode and increasing in an output power of the fuel cell, by suppressing adsorption onto the surface of the electrode of an air which is a by-product produced at the fuel electrode as well as by quickly removing the foamed air which is once adsorbed thereto.
摘要:
A fuel cell has a fuel electrode and an oxidizing agent electrode, a fuel supply path that supplies a liquid fuel to the fuel electrode, an oxidizing agent supply path that supplies an oxidizing agent to the oxidizing agent electrode, and an opening/closing member that, by changing its shape, opens and closes the oxidizing agent supply path. The change in the shape of the opening/closing member regulates the opening and closing of the oxidizing agent supply path.
摘要:
A production method and a production apparatus for stable mass production of nanocarbon are provided. In a production chamber (107), a graphite rod (101) having a cylindrical shape is fixed to a rotation apparatus (115), and is made to be capable of rotating with the length direction of the graphite rod (101) serving as an axis, and also moving to the right or the left in the length direction. The side surface of the graphite rod (101) is irradiated with a laser beam (103) from a laser light source (111), and a nanocarbon collecting chamber (119) is disposed in the direction of generation of plumes (109). On the other hand, the surface irradiated with the laser beam (103) among the side surfaces of the graphite rod (101) is speedily rotated by the rotation apparatus (115) and is flattened by a cutting tool (105). Cut dusts of the graphite rod (101) generated by the cutting tool (105) are collected into a cut graphite collecting chamber (121) and separated from the generated carbon nanohorn aggregates (117).

Nanocarbon is produced stably in a large amount. In a production chamber (107), a graphite rod (101) having a cylindrical shape is fixed to a rotation apparatus (115) and is made capable of rotating with its axis being in the length direction of the graphite rod (101) and movable to the right or the left in the length direction. A side surface of the graphite rod (101) is irradiated with a laser beam (103) from a laser light source (111). A nanocarbon collecting chamber (119) is disposed in the direction of generation of plumes (109) so as to collect the generated carbon nanohorn aggregates 117.

A fuel cell system includes a fuel cell main body which has a solid polymer electrolytic membrane, a fuel electrode and an oxidant electrode attached to the solid electrolyte membrane; a fuel storage unit which stores liquid fuel; a polymer membrane having a proton conductivity and provided in the fuel storage unit; a concentration detection unit (a first electrode terminal and a second electrode terminal) which detects the alcohol concentration of the liquid fuel in the fuel storage unit based on the alteration of the proton conductivity of said polymer membrane; and a concentration measurement unit.
摘要:
A plume (109) is generated by irradiating a side face of a graphite rod (101) with a laser beam (103) to vaporize carbon. The vaporized carbon is introduced to a carbon nanohorn recovery chamber (119) through a recovery pipe (155), and the vaporized carbon is recovered as a carbon nanohorn assembly (117). A cooling tank (150) including liquid nitrogen (151) is arranged in the recovery pipe (155). While the cooling tank (150) controls the plume (109) at a low temperature, the cooling tank (150) cools the carbon vapor when the carbon vapor passes through the recovery pipe (155). The cooled carbon vapor is recovered as the carbon nanohorn assembly (117) which is controlled in the desired shape and dimensions.
摘要:
A surface of a graphite target (139), irradiated with a laser beam (103), is formed in a plane. The graphite target (139) is held by a target holding unit (153) on a target supply plate (135). A plate holding unit (137) moves the target supply plate (135) in a translational manner, which allows an irradiation position of the laser beam (103) and the surface of the graphite target (139) to be relatively moved. A transportation pipe (141) communicated with a nanocarbon collecting chamber (119) is provided toward a direction in which a plume (109) is generated, and a generated carbon nanohorn aggregates (117) is collected in the nanocarbon collecting chamber (119).
摘要:
In an infrared ray sensor for a bolometer, a bridge structure body, a resistive element film for the bolometer, and a protection film is formed via a space on a substrate, and is formed into a solution form by dissolving metal organic compound into solvent. The solution is applied and dried. A laser ray is irradiated for the solution with wavelength of 400 nm or less. A bond between carbon and oxygen is decomposed and cut to thereby form an oxide thin-film.

Output properties of a fuel cell can be improved by using a single cell structure 1387 having an anode 102 and an oxidizing agent electrode 108 in both sides of a solid electrolyte membrane 114 and an evaporation inhibiting layer 1388 covering the surface of the cathode 108 which is not in contact with the solid electrolyte membrane 114.
