An acidic polymer hydrogel electrolyte was successfully prepared from 4 M H₂SO₄ aqueous solution, poly(vinyl alcohol) and glutaraldehyde. The polymer hydrogel electrolyte showed higher ionic conductivity than that prepared from 1 M H₂SO₄ aqueous solution in our previous study. An electric double layer capacitor (EDLC) cell assembled using the polymer hydrogel electrolyte exhibited higher discharge capacitance in the wide range of current density than that using the hydrogel electrolyte with 1 M H₂SO₄ aqueous solution.
