The present invention provides a hydrogen-storing carbonaceous material obtained by heating a carbonaceous material in a gas atmosphere including hydrogen gas and substantially including no reactive gas as impurity gas to store hydrogen. According to the present invention, since the surface of the carbonaceous material can be cleaned and hydrogen can be stored in the carbonaceous material in the same gas atmosphere and a hydrogen-stored carbonaceous material can be produced only by controlling a heating process time in the gas atmosphere including the hydrogen gas and substantially including no reactive gas as the impurity gas, not only a hydrogen storage device can be made compact, but also a hydrogen storage system can be simplified and a hydrogen storage process can be simplified.
A hydrogen-storing carbonaceous material obtainable by heating a carbonaceous material in a gas atmosphere including hydrogen gas and substantially including no reactive gas as impurity gas.
A producing method of a hydrogen-storing carbonaceous material comprising a step of heating a carbonaceous material in a gas atmosphere including hydrogen gas and substantially including no reactive gas as impurity gas.
A hydrogen-stored carbonaceous material obtainable by heating a carbonaceous material in a gas atmosphere including hydrogen gas and substantially including no reactive gas as impurity gas.
A producing method of a hydrogen-stored carbonaceous material comprising a step of heating a carbonaceous material in a gas atmosphere including hydrogen gas and substantially including no reactive gas as impurity gas.
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 heating a carbonaceous material in a gas atmosphere including hydrogen gas and substantially including no reactive gas as impurity gas to store hydrogen.
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 heating a carbonaceous material in a gas atmosphere including hydrogen gas and substantially including no reactive gas as impurity gas to store hydrogen, discharging hydrogen and supplying it to the anode.
