Abstract

The invention provides an apparatus for producing hydrogen and a method for producing hydrogen which effectively produce hydrogen in the low humidity atmosphere without humidifier or dehumidifier, and an electrochemistry device and a method for generating electrochemistry energy which generate electrochemistry energy by an oxidation-reduction reaction using hydrogen. A fullerene derivative where a proton (H+) dissociating group is introduced into a fullerene, is used as a composition material of a proton conductor 3, water is supplied to an anode 1 in a vapor or gas state and is electrolyzed, and produced protons (H+) are conducted to a cathode 2 through the proton conductor 3 and converted into hydrogen here. Moreover, hydrogen produced in such a way is decomposed into protons (H+) at the cathode 2, the protons are conducted to the anode 1 through the proton conductor 3 and converted into water there, and then, electrochemistry energy is extracted between the cathode 2 and the anode 1.
