A porous carbon catalyst exhibiting excellent catalytic activity and a method of producing the same, and an electrode and a battery. The porous carbon catalyst is obtained through carbonization of an organic polymer porous body having a skeleton containing a metal in an inside thereof. The porous carbon catalyst may have a skeleton containing the metal in an inside thereof, and the skeleton may be a particle aggregate-like skeleton. The method of producing a porous carbon catalyst includes carbonizing an organic polymer porous body having a skeleton containing a metal in an inside thereof.

Porous carbon catalyst, method for producing same, electrode and battery

Provided is a hydrogen-storing carbon material with improved hydrogen storage capacity. The hydrogen-storing carbon material has a total pore volume of 0.5 cm/g or more, and a ratio of a total mesoporous volume to a total microporous volume per unit weight of 5 or more. In addition, the hydrogen-storing carbon material may have a nitrogen content of 0.5 wt % or more and less than 20 wt %. In addition, the hydrogen-storing carbon material may have a stable potential of &#x2212;1.28 V or more when a cathode current with respect to the hydrogen-storing carbon material is held at 1,000 mA/g in electrochemical measurement by chronopotentiometry involving using the hydrogen-storing carbon material in a working electrode in a three-electrode method.
