An optical waveguide, a dielectric device and method for fabricating such devices in which a substrate is polarized in a first direction and a dielectric thin film is formed on the surface of the substrate and polarized in the opposite direction to the substrate. Parallel grooves may be formed in the substrate. In one embodiment, a first dielectric thin film is formed on the substrate and is formed with grooves and is polarized in the same direction as the substrate. Then, a second dielectric thin film is formed over the first dielectric thin film and it is polarized in a direction which is opposite to the substrate and the first thin film.

A fuel cell usable as a small-sized secondary cell such as a button type cell and a fuel cell system including the fuel cells are provided. The fuel cell has a first electrode, an electrolyte membrane, a second electrode, and a hydrogen storing material. The electrolyte membrane has polyfullerene hydroxide as a proton conductor. When a negative voltage is applied to the first electrode and a positive electrode is applied to the second electrode, protons, electrons, and oxygen are generated from water at the second electrode, and hydrogen is generated from the electrons and the protons at the first electrode. The hydrogen thus generated is stored in the hydrogen storing material, thus performing so-called charging. At the time of power generation, protons and electrons are generated, at the first electrode, from hydrogen supplied from the hydrogen storing material, and the generated protons are conducted to the second electrode via the electrolyte membrane and water is generated at the second electrode.
