发明名称 Sodium stannate additive to improve the durability of PEMS for H<sub>2</sub>/air fuel cells
摘要 An ion conducting membrane for fuel cell applications includes an ion conducting polymer and a tin-containing compound at least partially dispersed within the ion conducting polymer. The ion conducting membranes exhibit improved performance over membranes not incorporating such tin-containing compounds.

主权项 1. An ion-conducting membrane for fuel cell applications, the ion-conducting membrane comprising: an ion-conducting sulfonated tetrafluoroethylene-based fluoropolymer-copolymer; and a tin-containing compound at least partially dispersed within the ion-conducting sulfonated tetrafluoroethylene-based fluoropolymer-copolymer, the tin-containing compound being present in an amount from about 0.1 to about 5 weight percent of the total weight of the ion-conducting membrane, the tin-containing compound being described by formula I: MxSnO4  IM is hydrogen, sodium, potassium, calcium, or magnesium; andx is a number such that Mx balances the charge on SnO4.
