The present invention provides a hydrogen-stored carbonaceous material obtained by storing hydrogen in a carbonaceous material heated at more than 230° C. under a pressure reducing atmosphere, a battery and a fuel cell using this hydrogen-stored carbonaceous material. The carbonaceous material is heated at more than 230° C. under the pressure reducing atmosphere so that its surface can be efficiently cleaned and an area where the surface of the carbonaceous material comes into contact with hydrogen atoms or hydrogen molecules is increased.
A hydrogen-storing carbonaceous material obtainable by heating a carbonaceous material at more than 230° C. under the pressure reducing atmosphere.
A producing method of a hydrogen-storing carbonaceous material comprising a step of heating a carbonaceous material at more than 230° C. under the pressure reducing atmosphere.
A hydrogen-stored carbonaceous material obtainable by storing hydrogen in a carbonaceous material heated at more than 230° C. under the pressure reducing atmosphere.
A producing method of a hydrogen-stored carbonaceous material comprising a step of storing hydrogen in a carbonaceous material heated at more than 230° C. under the pressure reducing atmosphere.
A battery having an anode, a cathode and an electrolyte provided therebetween, wherein the anode and/or the cathode includes a hydrogen-stored carbonaceous material obtainable by storing hydrogen in a carbonaceous material heated at more than 230° C. under the pressure reducing atmosphere.
A fuel cell having a laminated structure of an anode, a proton conductor and a cathode, and a hydrogen storage part including a hydrogen-stored carbonaceous material obtainable by storing hydrogen in a carbonaceous material heated at more than 230° C. under the pressure reducing atmosphere, discharging hydrogen and supplying it to the anode.
