Definitions
- the present disclosure relates to a gasket member for a polymer electrolyte fuel cell, an electrode-electrolyte membrane laminate with a gasket member, and a polymer electrolyte fuel cell.
- a fuel cell is a battery in which electrodes are arranged on both sides of an electrolyte and generates electricity through an electrochemical reaction between hydrogen and oxygen, and only water is generated during power generation. As described above, unlike the conventional internal combustion engine, it does not generate environmental load gas such as carbon dioxide, so it is expected to spread as a next-generation clean energy system.
- Polymer electrolyte fuel cells in particular, operate at relatively low temperatures, have low electrolyte resistance, and use highly active catalysts. It is expected to be put into practical use at an early stage.
- This polymer electrolyte fuel cell first prepares a solid polymer electrolyte membrane having proton conductivity, forms an anode catalyst layer on one side of the electrolyte membrane, and forms a cathode catalyst layer on the other side of the electrolyte membrane.
- An electrolyte membrane laminate is produced, and a gas diffusion layer is further formed on each catalyst layer to produce an electrode-electrolyte membrane laminate.
- a gasket and a separator are installed on this electrode-electrolyte membrane laminate to complete a polymer electrolyte fuel cell (see, for example, Patent Document 1).
- Fuel cells operate in a humidified atmosphere to improve the proton conductivity of the electrolyte membrane, and since water is generated by the power generation reaction, the components that make up the fuel cell are also required to have high hydrolysis resistance.
- the output density can be improved by increasing the operating temperature of the fuel cell, use in a high temperature environment (for example, 100° C. or higher) is required from the viewpoint of downsizing the fuel cell.
- the gasket member does not necessarily have sufficient hydrolysis resistance in a high-temperature environment.

As a result, it is composed of a laminate comprising a base material layer and adhesive layers arranged on both sides of the base material layer, and the laminate has a breaking elongation after standing in water at 120° C. for 300 hours. It was found that a laminate having a degree retention of 60% or more has excellent hydrolysis resistance in a high-temperature environment and can be suitably used as a gasket member for polymer electrolyte fuel cells.
- Consists of a laminate comprising a substrate layer and adhesive layers arranged on both sides of the substrate layer, A gasket member for a polymer electrolyte fuel cell, wherein the laminate has a breaking elongation retention rate of 60% or more after standing in water at 120° C. for 300 hours.

破断伸度保持率は以下の方法で実施する。具体的には、120℃の水に浸漬し300時間静置した後、サンプルの破断伸度を測定し、得られた測定値を前記耐久試験前の破断伸度(初期破断伸度)で除算し、破断伸度保持率を求めた。破断伸度は、フィルムを幅(TD)15mm、長さ(MD)50mmの短冊状に裁断し、引張試験機を用いて、引張速度200mm/分、標線間距離を20mmの条件で引っ張ることにより破断するまでの伸度を測定した。試験環境は23℃とし、3回測定した平均値とする。
破壊伸度保持率(%)=耐久試験後の破断伸度÷耐久試験前の破断伸度(初期破断伸度)×100
熱間収縮率は、ガスケット部材を縦(MD)10cm×横(TD)10cmのサイズに切断した試験片を、150℃又は180℃のオーブン内で30分間加熱し、試験片の縦方向及び横方向(直交する2方向)における加熱前後の寸法変化率を下記式(I)に基づいて求め、2方向の寸法変化率の絶対値を平均値として算出したものである。
