摘要： A fuel cell contains an electrolyte sheet sandwiched between two electrodes. One or both electrode/electrolyte interfaces includes mesoscopic three-dimensional features in a prescribed pattern. The features increase the surface area-to-volume ratio of the device and can be used as integral channels for directing the flow of reactant gases to the reaction surface area, eliminating the need for channels in sealing plates surrounding the electrodes. The electrolyte can be made by micromachining techniques that allow very precise feature definition. Both selective removal and mold-filling techniques can be used. The fuel cell provides significantly enhanced volumetric power density when compared with conventional fuel cells.

摘要： In a fuel cell assembly comprising a plurality of cell each including an electrolyte layer (2), a pair of diffusion electrode layers (3, 4) interposing the electrolyte layer between them, and a pair of flow distribution plates (5) for defining passages (11) for fuel and oxidant fluids that contact the diffusion electrode layers, the fuel cells are arranged on a common plane. Therefore, the vertical dimension of the fuel cell assembly can be minimized, and a fuel cell assembly of favorable electric properties can be achieved. Each flow distribution plate is typically formed with communication passages for communicating fluid passages defined on each side of the electrolyte layer at a prescribed pattern. The communication passages and through holes communicate the fluid passages in such a manner that adjacent fuels cells have opposite polarities.

摘要： In a fuel cell comprising a tubular casing, an electrolyte layer received in the tubular casing, and a pair of gas diffusion electrodes interposing the electrolyte layer and defining a fuel gas passage and an oxidizing gas passage, respectively, each gas diffusion electrode is formed by stacking a plurality of layers of material therefor, for instance in the axial direction of the casing. Because the gas diffusion layers are formed layer by layer, components can be formed in highly fine patterns so that a highly compact tubular fuel cell can be achieved. Similarly, the dimensions of the various elements of the fuel cell can be controlled in a highly accurate manner. Also, the geometric arrangement can be changed at will in intermediate parts of each gas passage.
