Abstract
The present invention provides new compounds for use in proton exchangemembranes which are able to operate in a wide variety of temperature ranges, including in the intermediate temperature range of about 100° C. to 700°C., andnew and improved methods of making these compounds. The present invention also provides new and improved methods for making chalcogenide compounds, including, but not limited to, non-protonated sulfide, selenide and telluridecompounds. In one embodiment, the proton conductivity of the compounds is between about 10−8 S/cm and 10−1 S/cm within a temperature range of between about −50 and 500° C.
