Title PROTON CONDUCTOR AND FUEL CELL
Abstract A first proton-donating layer (20a) is a layer having a proton-donative functional group on the surface thereof, for example, a silicon oxide layer. A second proton-donating layer (20b) is also a layer having a proton-donative functional group on the surface thereof, for example, a silicon oxide layer. Negative surface charges are formed on the main surface section of a first substrate (10a) and the main surface section of a second substrate (10b), and these negative charges increase the conductivities of the protons in the aqueous solution supplied to a nano channel. Although, in the aqueous solution, proton migration due to hopping between water molecules contribute to diffusion, the negative charges formed on the main surfaces of the substrates (10a, 10b) attract protons in the aqueous solution, and the conduction of protons is efficiently achieved in a "high-speed transfer region" formed around the proton-donating layers (20a, 20b), so that the effect of increasing the proton conductivity can be achieved.
