Apparatus for producing hydrogen, electrochemical device, method for producing hydrogen and method for generating electrochemical enegy

An electrochemistry device using a reversible reaction of decomposition and generation of water and hydrogen comprising:

• an anode and a cathode which are placed in the opposite direction;
• and
• a proton conductor which is located between the anode and the cathode and has a structure containing a carbon material which is at least one kind selected from the group consisting of fullerenes, carbon clusters, and linear carbon structures where a proton (H+) dissociating group is introduced into at least a part of carbon atoms.
