Abstract:
1. A fuel cell which comprises a cathode, an anode, a solid polymer electrolyte sandwiched therebetween, a means to supply oxygen as an oxidizing agent gas to the cathode, a means to supply hydrogen as a reducing agent gas to the anode, wherein the cathode has electroconductive polyaniline, polyalkylaniline, or polyindole as a p-type electroconductive organic polymer and the anode has electroconductive poly(o-phenylenediamine), polypyridine, polyquinoxaline, or polyphenylquinoxaline as an n-type electroconductive organic polymer, each as an electrode catalyst, and wherein both of the electroconductive organic polymers have an oxidation-reduction function, contain a polymer sulfonic acid as a dopant and are admixed with and an inorganic oxidation-reduction catalyst.
