USE OF A CELL COMPONENT IN FUEL CELL

摘要

An electrochemical cell component having two planarly disposed electrodes bonded to or intimately pressed against opposing sides of a proton exchange active film; said film having: (a) sulfonyl ion exchange active groups present in their protonated form; (b) an equivalent weight of less than about 1000; and (c) a storage modulus of greater than about 1 x 10<8> dynes/square centimeter at a temperature greater than about 110C. The invention is particularly useful in proton exchange polymer film fuel cells.
