The present invention relates to a method for manufacturing a fuel cell separator, in which a current collecting protrusion is formed by etching.

〔発明の背景〕[Background of the invention]

溶解塩型燃料電池は、その構成部材のうち、セパレータ
として導電性を有する金属を用いると共に、電解質板と
してセラミックスを用いている。Among its constituent members, a molten salt fuel cell uses conductive metal as a separator and ceramics as an electrolyte plate.

を極性をそろえて順次積み重ねて構成されている。In order to obtain a large capacity battery output, this fuel cell has an anode on one side of an electrolyte plate, a cathode on the other side of the electrolyte plate, and a separator on both sides. It consists of unit batteries, and these unit batteries are stacked one after another with the polarities aligned.

来は機械加工によっていた。Such a molten salt fuel cell has an operating temperature of 650 to 7
Since the temperature is as high as 00'C, the materials used for the separator are limited to metal materials from the viewpoint of heat resistance. Also,
Since alkaline molten carbonate is used as the electrolyte, the material used for the separator is stainless steel, which is highly corrosion resistant. By the way, machining has conventionally been used as a method for forming the fuel chamber, the oxidizer chamber, and the protrusions of the current collector provided in both chambers in a separator made of such a stainless steel material.

材料を使用せざるを得ない。このため、燃料電池の小型
軽量化が図れないという大きな欠点がある。The method of forming the separator by machining is suitable because the finish of the separator can maintain high precision. However, according to such conventional manufacturing methods, the separator is easily affected by thermal distortion that occurs during cutting. Furthermore, according to such conventional manufacturing methods, if the thickness of the separator material is less than 5 to 6 [m], it is difficult to process. I have no choice but to use . For this reason, there is a major drawback in that the fuel cell cannot be made smaller and lighter.

A metal material that has been processed to have the dimensions of a separator and smoothed on both sides is covered with an etching mask that first etches the dimensions to match the thickness of the electrode, and is immersed in an etching solution for a predetermined period of time. After processing the step trench, the mask is covered with a mask shaped so that the fuel or oxidizing gas is highly dispersed throughout the room and current collection can be carried out at a high rate. By carrying out the two-stage drilling process, a separator in which a fuel chamber, an oxidizing agent chamber, and a current collecting protrusion are formed is obtained.

エツチングする。Next, as a second stage moat, the fuel chamber 12 is constructed with a depth of 1.5 [degrees], an area of 290 [simplified], and a current collecting protrusion as shown in Fig. 4, but actually as shown in Fig. 5. 13 is etched so that the width is 2 (ma) and the width of the fuel chamber 12, that is, the recess is 3 [■].Furthermore, the fuel passage 14 is etched so that the width of the fuel chamber 12, that is, the recess is 3 [■].
There are 4 oxidizer chambers on one side with 16 oxidizer chambers on the back side.
The current collector protrusion 17 and the oxidizer passage 18 are etched at the same time so that they have exactly the same shape as the current collector protrusion 13 of the fuel chamber 12 and are orthogonal to each other.

As shown in the figure, for example, if the top surface of a round shape is designed to have a diameter of 4 [sm], the finish will be about 3.8 (sm), and if the depth of the hole is between 1 and 1.5 [s. The diameter was increased to 5.5 [audible], and a shape suitable for current collection was obtained.

で完成させることができた。If the separator is formed by etching, firstly, if the trench depth of the fuel chamber and the oxidizer chamber on the other side through the partition are the same, it is possible to work on both sides at the same time, which reduces the manufacturing time.
It will be shortened to one-fold. In addition, while it takes about 40 hours to form one separator on one side using the conventional manufacturing method using machining, the manufacturing method according to the present invention takes only about 3 hours to form both sides at the same time.
