POLYELEKTROLYT OG FREMGANGSMÅDE TIL FREMSTILLING AF POLYELEKTROLYTTEN

The present invention provides an electrolyte having high conductivity even under high-temperature low-humidification conditions (e.g. at a temperature of 100 to 120°C and a humidity of 20 to 50% RH) and thereby makes it possible to realize a higher performance fuel cell. The present invention is a...

Beschreibung
Zusammenfassung:	The present invention provides an electrolyte having high conductivity even under high-temperature low-humidification conditions (e.g. at a temperature of 100 to 120°C and a humidity of 20 to 50% RH) and thereby makes it possible to realize a higher performance fuel cell. The present invention is a fluoropolymer electrolyte having an equivalent weight (EW) of not less than 250 but not more than 700 and a proton conductivity of not lower than 0.10 S/cm as measured at a temperature of 110°C and a relative humidity of 50% RH and comprising a COOZ group- or SO 3 Z group-containing monomer units, wherein Z represents an alkali metal, an alkaline earth metal, hydrogen atom or NR 1 R 2 R 3 R 4 if which R 1 , R 2 , R 3 and R 4 each independently represents an alkyl group containing 1 to 3 carbon atoms or hydrogen atom.
