    摘要: An electrolyte for a fuel cell includes an electrolyte body, a plurality of microstructures formed into or extending out of the electrolyte body, and thin film layers formed on the electrolyte body. A microstructure possesses a depth or a height and includes one or more sidewalls and a bottom surface. A sidewall of the microstructure advantageously creates a significant unobstructed diffusion area, wherein protons may travel laterally into or out of the electrolyte body. Therefore, when a proton is generated by the interaction of the fuel with a thin film catalyst layer, the proton may travel laterally only a short distance in order to enter or exit the electrolyte body, thereby improving the performance of the fuel cell.

    摘要: An electric energy generating apparatus configured to generate a desired electromotive force from hydrogen and oxygen. The apparatus comprises a hydrogen electrode film, an electrolyte film and an oxygen electrode film. The hydrogen electrode film, to which hydrogen is supplied, comprises a catalyst layer containing a decomposing catalyst that decomposes hydrogen into protons and electrons. The electrolyte film comprises a sheet having a plurality of voids. Oxygen is supplied to the oxygen electrode film. The voids in the electrolyte film are filled with proton-conducting material and/or the decomposing catalyst. This prevents the hydrogen from reaching the oxygen electrode film. When hydrogen is supplied to the hydrogen electrode film, the concentration of hydrogen of the oxygen electrode therefore decreased to such a value as required generating the desired electromotive force.

The electrode catalyst layer is made of carbon black carrying a PtnullMn-based alloy such as a PtnullMn alloy on its particle surface. For operating the fuel cell which includes the cathode electrode, it is preferable to make the pressure of an oxygen-containing gas supplied to the cathode electrode higher than the pressure of an hydrogen-containing gas supplied to an anode electrode to make the pressure at the cathode electrode higher than the pressure at the anode electrode.
