摘要:
An adhesive member is used to bond one member to another member to form an adhesive layer whose internal defection can be detected by utilizing a magneto-mechanical property of a soft magnetic material. The adhesive member is comprised of a main body formed of an uncured adhesive, and a plurality of soft magnetic materials embedded in the main body and restrained in an external force-applied state after curing of the main body.

In measuring the stress of a ferromagnetic linear metal member, an alternating current is supplied to flow between a pair of terminals mounted to the ferromagnetic linear metal member to measure an impedance .vertline.Z.vertline. of the ferromagnetic linear metal member between the terminals by an analyzer. Then, a stress .sigma. is determined based on the measured value of the impedance .vertline.Z.vertline. from an impedance .vertline.Z.vertline.-stress .sigma. relationship possessed by the ferromagnetic linear metal member. The stress distribution in a sheet-like sensor can be likewise measured by inserting into the sensor a plurality of intersecting ferromagnetic linear metal members. The stress .sigma. is determined for each individual member as described above, and then the stress distribution in the sheet-like sensor is determined by summing up the stresses of mutually intersecting members.

A method for forming a carbon nanotube (5) on an electroconductive member (2). A catalytic layer (3) including a metal or alloy that serves as a catalyst for growing the carbon nanotube is formed on an electroconductive member, the metal or alloy of the catalytic layer is processed so as to turn it into small particles (3a) by heating the catalytic layer formed on the electroconductive member to a prescribed temperature while supplying inert gas, and a carbon nanotube is grown on the electroconductive member by using the small particles of the metal or alloy of the catalytic layer as a catalyst. The fine metallic particles that can be used as a catalyst for growing the carbon nanotube can be prepared in a simple, economical and efficient manner. The carbon nanotube is highly suitable for use as the diffusion layer of a fuel cell.

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.
