Abstract

PURPOSE:To obtain an economical fuel cell with a number of single cells laminated whose mainframe is not influenced by thermal expansion and shrinkage by arranging a carbon terminal block on both ends of the fuel cell and mounting a flexible terminal on it. CONSTITUTION:A carbon terminal block 5 made of a metal graphite material is arranged on both ends of a fuel cell mainframe in which a number of single cells are laminated and a mounting hole 7 is provided on its end face. A flexible terminal 6 with a twisted narrow conductor to which resistance to strong acids surface treatment is applied is inserted in the hole and is fixed by packing copper powder or the like 8 and then the inlet section is sealed with a sealant 9. Then the current generated in the fuel mainframe is externally guided from the carbon terminal block 5 that makes contact to the single cell on the outermost layer through the flexible terminal 6. As a result, the economical fuel cell can be obtained without using gold plating, etc. and cannot be influenced by the thermal expansion and shrinkage.

Conventionally, the device shown in FIG. 1 has been used as a device of this type. In the figure, (1) is a single cell, a fuel cell body formed by stacking +21ff multiple layers, and (3) is a terminal plate arranged at both ends of this fuel cell body 111, which is a gold-plated steel plate. consists of things.

1 and is taken out to the outside from the terminal (4). However, in the conventional device described above, the terminal plate L31 and the terminal (4) T- are obtained by gold plating the steel plate, making it very expensive. . In addition, since the terminal (4) is a rigid body, there are disadvantages such as the need for a mechanism (not shown) to absorb the thermal expansion and contraction of the fuel cell body or the connecting conductor (not shown). there were.

体などの熱膨張、熱収縮を吸収することができ、るＯThis invention was made in view of the above-mentioned drawbacks of the conventional ones, and by arranging carbon terminal plates at both ends of the fuel cell body and attaching flexible terminals to the carbon terminal plates, it is economical. The purpose of the present invention is to provide a terminal device for a fuel cell that can absorb thermal expansion and contraction of the fuel cell main body. This will be explained based on Figure 3. In each of these figures, 1lil is a carbon terminal plate made of, for example, metal graphite, which is arranged at both ends of the fuel cell body +11, 1g1r! A flexible terminal is attached to the end face of this carbon terminal plate (!I), and is formed by twisting together thin conductors that have been treated with a strong acid-resistant fitting surface. The flexible terminal (6) is inserted into the terminal mounting hole (7) in the terminal mounting hole (7). conductive metal powder, T91RJ, and a sealing material that seals from the outside environment.Next, we will explain the operation of the flexible terminal (6 ) into the mounting hole (1) of the carbon terminal plate il+, and fill the gap between the flexible terminal (6) and the cast hole ()) with copper powder and conductive metal powder (8). The flexible terminal (6) is firmly attached to the carbon terminal plate (6). After that, apply the sealant (
9) Seal the entrance 'm of the mounting hole (7).◇The carbon terminal plates (6) to which the flexible terminals (6) are thus attached are arranged at both ends of the fuel cell main body 11+. By the way, the carbon terminal plate (6) that comes into contact with the outermost cell (2) is connected to the electric flt generated in the fuel cell main body (1).
Since there is no need for gold plating as in the case of 0 or more which is taken out from the flexible terminal (8) to the outside, it becomes inexpensive. In addition, the fuel cell main body (1
) or can easily absorb the thermal expansion and contraction of the connecting conductor.In addition, in the above embodiment, the case where the carbon terminal plate [1] is made of metal graphite is described, It is also possible to use a carbon terminal plate made of a carbon mold made of impregnated metal graphite and copper steel. By attaching a flexible terminal 1D to the carbon terminal plate, it is economical and can absorb thermal expansion and contraction of the fuel cell body, etc.
