Abstract
An electrolyte for an electrochemical cell is provided. The electrolyte is an admixture of H.sub.3 PO.sub.4 and a high temperature polymer such as poly(benzimidazole) in ratios between 2:1 and 50:1, Fumed silica is added to the electrolyte at levels between 0.2% and 8% by weight. An electrochemical cell is fabricated using the electrolyte, and exhibits improved adhesion between the electrolyte and the electrode.
