Abstract
This invention relates to a cell electrode comprising a proton-conducting compound capable of being involved in a redox reaction in a solution of an electrolyte containing a proton source as an electrode-active material and a cation exchanger, and an electrochemical cell therewith.
Claims20
A cell electrode comprising a proton-conducting compound, as an electrode-active material, capable of being involved in a redox reaction in an electrolytic solution containing a proton source, and a cation exchanger.
A cell electrode comprising:
- an electrode-active material constituted by a proton-conducting compound for performing a redox reaction in an electrolytic solution containing a proton source;
- and
- a cation exchanger dispersed at least in a surface layer of the cell electrode in an amount effective to trap an impurity such as iron ions involved in the redox reaction.
