Abstract:
1. A proton conductor material comprising a sulfonated amorphous carbon, wherein the sulfonated amorphous carbon has a sulfonate density of 1.6 to 8 mmol/g, in the sulfonated amorphous carbon, chemical shifts of a condensed aromatic carbon 6-membered ring and a condensed aromatic carbon 6-membered ring having a sulfonate group bonded thereto are detected in a at least a diffraction peak of carbon (002) face whose half-value width (2θ) is in the range of 5 to 30 is detected in powder X-ray diffractometry, and the sulfonated amorphous carbon exhibits proton conductivity.
