An electrode includes a composite mixture layer formed by applying a composite mixture having one of a cathode active material or an anode active material on one of main surfaces of a plurality of current collectors formed in substantially rectangular shapes; and a non-applied part to which the composite mixture is not applied at both end parts in the longitudinal direction. One current collector is connected to the other adjacent current collector at one end side in the longitudinal direction through a connecting part to which the composite mixture is not applied and which is provided continuously to the non-applied parts. In the electrode constructed as described above, a plurality of current collectors can be laminated to obtain a multi-layer structure and an electric current can be collected from a lead welded to only one end part of the current collector. Thus, the electrode of a new form having an excellent productivity and a high capacity can be provided.

An electric energy generating apparatus configured to generate a desired electromotive force from hydrogen and oxygen is provided. The apparatus includes a hydrogen electrode film, an electrolyte film and an oxygen electrode film. The hydrogen electrode film, to which hydrogen is supplied, includes a catalyst layer containing a decomposing catalyst that decomposes hydrogen into protons and electrons. The electrolyte film includes 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.

A powder beam working system for working a surface to be worked of an object to be worked by dispersing fine particles in high-pressure gas and projecting a solid-gas two-phase flow thus produced to the surface of the object to be worked which comprises means which temporarily stores the fine particles, a dispersing chamber which forms a portion of a flow path for the high-pressure gas and sending means which sends out the fine particles stored in the storing means into the dispersing chamber at a predetermined rate as the fine particles are in a solid phase state, thereby being capable of adjusting a flow rate of the produced solid-gas two-phase flow and an amount of the fine particles contained in the solid-gas two-phase flow easily and individually.
