Abstract
A chemical fullerene derivative is for a proton conducting membrane electrolyte, in which sulfonic acid group SOM and/or phosphonic acid group PO(OM)is directly bonded, but an organic compound is substantially not bonded. A production method is for the chemical fullerene derivative, which uses dimethylacetamide plus water in the case of sulfonation reagent KSOand dioxane in the case of phosphonation reagent LiPO(OEt).
