CA 2451114

A proton conductor which comprises a carbon cluster having a functional group capable of releasing a proton and a substance having a moiety capable of accepting a proton, or which comprises a substance capable of releasing a proton and a carbon cluster having a moiety capable of accepting a proton. A carbon cluster, in particular, a carbon cluster having a specific structure such as fullerene or carbon nanotube has proton conductivity also in a dry condition, and exhibits markedly improved proton conductivity when combined with a substance capable of accelerating the dissociation of a proton. Accordingly, the present proton conductor requires no replenishment of moisture and can be used also in a dry atmosphere and at a high temperature.

L'invention concerne un conducteur protonique comprenant un agrégat de carbone doté d'un groupe fonctionnel capable de libérer un proton et une substance dotée d'une fraction capable d'accepter un proton, ou comprenant une substance capable de libérer un proton et un agrégat de carbone doté d'une fraction capable d'accepter un proton. Un agrégat de carbone, notamment un agrégat de carbone comprenant une structure spécifique, telle qu'un fullerène ou un nanotube de carbone présente une conductivité protonique également à l'état sec et une conductivité protonique notablement améliorée lorsqu'il est combiné à une substance capable d'accélérer la dissociation d'un proton. De ce fait, le conducteur protonique ne nécessite pas d'apport d'humidité et peut être utilisé dans une atmosphère sèche et à température élevée.
