Electrode for electrochemical cell and electrochemical cell therewith

The present invention relates to an electrode for an electrochemical cell which comprises a cathode containing a proton-conducting compound as an electrode active material, an anode containing a proton-conducting compound as an electrode active material and an electrolyte containing a proton source, comprising a proton-conducting compound such as π-conjugated compounds or polymers having nitrogen atom, quinone compounds and quinone polymers, e.g. indole trimer, quinoxaline polymer and an anion-exchange resin. This invention can be used to improve cycle-life properties and high-speed charge/discharge properties in an electrochemical cell.
