Abstract

An electrolyte system (40) for use in connection with an electrochemical cell (10). The cell (10) includes a positive (20) and a negative (30) electrode, and an electrolyte system (40) disposed therebetween. The electrolyte system includes a polymer matrix fabricated of a polyacrylic acid or polyacrylic acid derivative polymeric material. The polymer material is adapted to engage in electroactive species. Examples of electroactive species may be either an acid or a base electrolyte, such as KOH or H.sub.2 SO.sub.4.
