An electrolyte membrane comprises a porous membrane and a proton conductive inorganic material loaded in the porous membrane. The proton conductive inorganic material has a super strong acidity. The proton conductive inorganic material contains a first oxide and a second oxide bonded to the first oxide. The first oxide contains an element X formed of at least one element selected from the group consisting of Ti, Zr, Hf, Nb, Al, Ga, In, Si, Ge, Sn and Ce. The second oxide contains an element Y formed of at least one element selected from the group consisting of V, Cr, Mo, W and B. |
