FLUORINATED PHOSPHONIC SULFONIC ACIDS AND DERIVATIVES THEREOF

摘要

2045151 9007513 PCTABS00001 The present invention provides compounds comprising one or more fluorine atoms, sulfo radicals and phosphono radicals, each such radical being bonded to the same or different carbon atom, with the proviso that at least one sulfo radical and at least one phosphono radical are bonded to such carbon atoms through the sulfur atom and the phosphorus atom, respectively. These compounds are preferably non-polymeric, i.e. they have a molecular weight of about 5000 or less. Such compounds are useful as electrolytes, e.g. in fuel cells.
