SOLID HIGH POLYMER ELECTROLYTE FILM AND FUEL CELL

摘要

PROBLEM TO BE SOLVED: To provide a solid high polymer electrolyte that can provide a fuel cell, which can maintain high voltage also in long-term operation or high temperature operation and has excellent stability. SOLUTION: It consists of an organic resin and hydrate oxide antimony particles expressed with a formula Sb2 O5 .nH2 O (n=0.1 to 5). Average particle diameter of this particles is in the range of 5 to 50 nm, and the content of hydrate oxide antimony particles is in the range of 5 to 80 weight % by converting it to the oxide (Sb2 O5 ).
