A superconducting material higher in superconducting transition temperature and superconducting volume ratio than any conventional one is provided, which comprises a fullerene doped with rubidium and cesium. This fullerene system superconducting material makes it possible to improve both the superconducting transition temperature and superconducting volume ratio by having rubidium and cesium doped thereinto compared with any conventional fullerene systems. If the chemical composition of this super conducting material is expressed as Rb.sub.x Cs.sub.y C.sub.n, x and y are arbitrary if an equation x+y=3 is satisfied, preferable to be x=2 and y=1, further preferable to be x=1 and y=s. The superconducting transition temperature Tc and superconducting volume ratio when x=1 and y=2 or x=2 and y=1 are superior to those when x=3 and y=0 or x=0 and y=3, respectively.

摘要:
Electric power is supplied from a fuel cell to a portable personal computer (210) having a heat-producing section (212) which generates heat during operation. The fuel cell includes electrolyte, a fuel electrode and an oxidant electrode arranged to sandwich the electrolyte, and a fuel supply section capable of supplying fuel which has absorbed heat of the heat-producing section (212) to the fuel electrode. The fuel supply section removes the heat from the heat-producing section (212) by supplying fuel to the fuel electrode when the fuel is heated by heat exchange. Thus, it is possible to improve the battery efficiency of the fuel cell and suppress increase of the temperature of the heat-producing section.
摘要:
A plurality of fuel electrodes are disposed on one surface of a solid polyelectrolyte membrane, while a plurality of oxidizer electrodes are disposed on the other surface of the same to create a plurality of unit cells which share the solid polyelectrolyte membrane. These unit cells are electrically connected through connection electrode extending through the solid polyelectrolyte membrane. A groove is formed in a region of the solid polyelectrolyte membrane between adjacent unit cells. This groove limits the migration of hydrogen ions to adjacent unit cells to prevent a reduction in voltage. The resulting solid polymer fuel cell, which is in a simple structure and reduced in size, can provide high power.

摘要:
The present invention provides a solid electrolyte type fuel cell that can control a cross-over, and implements the high fuel efficiency and the high output of the fuel cell. A substance is dissolved to a fuel 124, and does not permeate a solid polymeric electrolyte film 114. Because of this, on an interface between the solid polymeric electrolyte film 114 and the fuel 124 in a fuel electrode 102, an osmotic pressure in a direction from an oxide agent electrode 108 to a fuel electrode 102 is generated. Because of this, the water movement from the fuel electrode 102 side to the oxidizing agent electrode 108 side is controlled, and the cross-over of the fuel is controllable.
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:
An oxygen reduction catalyst and the catalyst as an electrode catalyst are provided. The oxygen reduction catalyst is characterized by including an organometallic polymer structure in which a transition metal or zinc is coordinated with an organic polymer compound including a ligand comprising a heterocyclic 5-membered ring or a heterocyclic 6-membered ring containing at least not less than two elements selected from nitrogen (N), oxygen (O), sulfur (S), and selenium (Se), and derivatives thereof. Thereby, even when an amount of a metal is smaller than that in a platinum particulate catalyst, an oxygen reduction capacity equal to or more than that of the platinum particulate catalyst can be obtained. Further, by coordinating a metal with an organic polymer, stability in an oxygen reduction condition can be significantly improved compared to the case of metal based macrocyclic compounds.

An adhesion layer containing a second solid polymer electrolyte is disposed between a solid polymer electrolyte membrane and a fuel electrode and/or an oxidant electrode containing a first solid polymer electrolyte and a catalyst substance.

In this manner, the adhesion at the interface between the electrode surface and the solid polymer electrolyte membrane is enhanced to implement the elevation of the cell characteristics and the elevation of the reliability of the cell.
