1. A fuel cell comprising:

  • a first electrode having a catalyst for generating hydrogen;

    a second electrode having a catalyst for generating oxygen, said second electrode being provided while allowed to be in contact with water; and

    a proton conductive electrolyte membrane having a proton conductor produced by introducing proton dissociative groups into a base body composed of a carbonaceous material containing carbon as a main component, said electrolyte membrane being provided between said first electrode and second electrode;

    wherein when a negative voltage is applied to said first electrode and a positive voltage is applied to said second electrode, oxygen, protons and electrons are generated from water under the presence of said catalyst at said second electrode, and hydrogen is generated from the protons and the electrons under the presence of said catalyst at said first electrode.
