Elektrochemische Polymermembranzelle mit Betriebstemperatur über 100 C |
摘要 |
The invention concerns a proton exchange membrane comprising a perfluorosulfonic acid having silica particles embedded therein in a concentration by weight comprised between 0.01 and 50% by weight and dimensions comprised between 0.001 and 10 micrometers, characterized in that said membrane comprises both an amorphous and a crystalline phase and the ratio thereof is adjusted by means of a controlled thermal treatment at a temperature higher than the glass transition temperature, controlled by an X-ray spectrometer. The invention further concerns an electrochemical cell using said membrane, in particular a fuel cell and the method of operating the same. |
