Problems solved by technology

[0013] In addition, the general electrochemical cell evaluation holders including the devices disclosed in the above-mentioned documents have the problem of adopting a vertical triple tube structure in which the cell is sandwiched from both pole sides by the gas introduction tubes, and thus can only be used with For the electric furnace corresponding to this, in addition, since the holder itself is large, it is inconvenient to handle when installing

Embodiment Construction

[0038] Hereinafter, the form for implementing this invention is demonstrated in detail, referring drawings. In addition, this invention is not limited by this embodiment, The other form, an Example, operation technique, etc. which can be implemented based on this aspect by those skilled in the art etc. are all included in the category of this invention.

[0039] First, while referring to figure 1 , the configuration of the electrochemical cell evaluation holder according to the present invention will be described.

[0040] Such as figure 1 or figure 2 As shown, the structure of the electrochemical cell evaluation holder 1 of this example is such that the clamping parts 30 are clamped between the fuel electrode side case 10 (lower in the figure) and the air electrode side case 20 (upper in the figure). The state in between is fastened and fixed by the fixing member 40 and assembled.

[0041] The fuel electrode case 10 has a rectangular parallelepiped shape made of alumina wh...

Abstract

The invention provides a retainer for the evaluation of an electrochemical cell, wherein the adverse effect on the electrochemical cell when no performance evaluation is provided is eliminated, while the miniaturization of equipment is realized. In this way, electric furnaces are easily set and assembled. According to the technical scheme of the utility model, a fuel gas diffusion plate (31) served as a clamping part (30), a fuel electrode current collector (32), a unit part (34), a pair of ceramic pads (33), an air electrode current collector (35) and an air gas diffusion plate (36) are laminated, and a fuel-electrode-side accommodation recess (11) and an air-electrode-side accommodation recess (21) are arranged opposite to each other. A fuel-electrode-side housing (10) and an air-electrode-side housing (20), both of which are made of alumina material, are clamped in a mutually docked. Then a clamping part (30) is clamped between the fuel-electrode-side housing (10) and the air-electrode-side housing (20). A ceramic spring (43) is inserted into an air-electrode-side through hole (26) and a bolt (41) inserted into a fuel-electrode-side through hole (16) to be tightly fixed so as to complete the assembling process.

Description

technical field [0001] The present invention relates to a holder for electrochemical cell evaluation for evaluating performance characteristics of a solid oxide fuel cell (SOFC) using a flat-plate cell. Background technique [0002] A solid oxide fuel cell (Solid Oxide Fuel Cell: SOFC) is a fuel cell that uses an oxygen-ion-conducting solid electrolyte as an electrolyte, and supplies two gases, fuel and oxidant, to the fuel separated by an oxygen-ion-conducting solid electrolyte. The electrode and the air electrode perform an electrochemical reaction at each electrode, whereby electric power is taken out to the outside. [0003] The solid oxide fuel cell, as a low-pollution and high-efficiency power generation method, can miniaturize the device due to its high operating temperature and high output density. In pursuit of overall high efficiency (cogeneration), research and development are progressing for practical use as large-scale power generation systems or decentralized ...
