<P>PROBLEM TO BE SOLVED: To provide a proton conductive polymer battery, using electrodes containing electro-conductive compounds of proton conductivity as active materials composed of aqueous electrolyte solution, excellent in battery characteristics even if reflow process is performed, having high safety and reliability. <P>SOLUTION: In the proton conductive polymer battery; a positive electrode and a negative electrode are placed oppositely through a separator in electrolyte solution, and electrode active materials in the positive and negative electrodes are selected from π-conjugated system polymers and hydroxyl group containing polymers and only proton participates in charging and discharging. The electrolyte solution is an aqueous solution containing sulfuric acid as an electrolyte, a part of content water is substituted by at least either of phosphoric acid or diphosphoric acid, ratio of concentration of sulfuric acid in the solution is from 3 to 35 wt.%, and concentration of content water is 65 wt.% or less. <P>COPYRIGHT: (C)2007,JPO&INPIT |
