This invention relates to a polymer having a chain structure of a repeating unit of a proton-conducting compound which causes an electrochemical redox reaction in a solution of a proton source to act as an electrode active material, and a heterocyclic compound structure; and an electrochemical cell comprising the polymer as an electrode active material.

Polymers and electrochemical cell therewith

This invention provides an electrode comprising a porous conductive substrate as well as an electrode active material and a conductive auxiliary filled in the pores in the substrate. This electrode exhibits improved shape stability (strength), a lower resistivity and better response. This electrode can be used to provide an electrochemical cell capable of quick charge/discharge and exhibiting improved cycle properties.
