フルオロオレフィン、シクロヘキシル基含有アクリル酸エステル、水酸基含有ビニルエーテルを構成成分とする含フッ素共重合体(関東電化工業社製KD200)の30質量%酢酸エチル溶液に、架橋剤としてヘキサメチレンジイソシアネートをKD200のOH価の1.4倍当量になるように溶解して、塗工液を調製した。得られた塗工液を、厚さ50μm、大きさ20cm×30cmの二軸延伸PENフィルム(帝人デュポン社製テオネックス:片面易接着処理品)の易接着処理面にワイヤーバーコーターで塗工し、140℃で1分間熱処理後、70℃で48時間熱処理し、塗工厚1μmのフッ素樹脂コートPENフィルムを得た。得られたフィルムを外寸8×8cm、内寸5×5cmの額縁状に打ち抜いた後、そのコーティング面を厚さ30μm、外寸8×8cmの固体高分子電解質膜(ジャパンゴアテックス社製ゴアセレクト)と重ね合わせ、熱プレスにより160℃で5分間熱圧着し、PENフィルム補強高分子電解質膜を得た。
片面をコロナ放電処理した厚さ50μm、大きさ20cm×30cmのPPSフィルムの該処理面に、実施例1と同様の塗工液を実施例1と同様の方法で塗布し、塗工厚1μmのフッ素樹脂コートPPSフィルムを得た。同様に得られたフィルムを外寸8×8cm、内寸5×5cmの額縁状に打ち抜いた後、そのコーティング面を厚さ30μm、外寸8×8cmの固体高分子電解質膜(ジャパンゴアテックス社製ゴアセレクト)と重ね合わせ、熱プレスにより160℃で5分間熱圧着し、PPSフィルム補強高分子電解質膜を得た。
片面にアクリル系粘着材を適用した厚さ50μm、外寸8×8cm、内寸5×5cmの額縁状のPENフィルムの該粘着面を、厚さ30μm、外寸8×8cmの固体高分子電解質膜(ジャパンゴアテックス社製ゴアセレクト)と重ね合わせ、圧着しPEN補強高分子電解質膜を得た。
外寸8×8cm、内寸5×5cmの額縁状の片面易接着処理PENフィルム(帝人デュポン社製テオネックス:片面易接着処理品)の易接着面を厚さ30μm、外寸8×8cmの固体高分子電解質膜(ジャパンゴアテックス社製ゴアセレクト)と重ね合わせ、熱プレスにより160℃で5分間熱圧着し、PENフィルム補強高分子電解質膜を得た。
大きさ20cm×30cmの片面易接着処理PENフィルム(帝人デュポン社製テオネックス:片面易接着処理品)の易接着面に酢酸ビニル樹脂エマルジョン(PVAC)接着剤をワイヤーバーコーターにて塗工し、80℃で3分間乾燥し、塗工厚3μmのPVACコートPENフィルムを得た。得られたフィルムを外寸8×8cm、内寸5×5cmの額縁状に打ち抜いた後、そのコーティング面を厚さ30μm、外寸8×8cmの固体高分子電解質膜(ジャパンゴアテックス社製ゴアセレクト)と重ね合わせ、熱プレスにより160℃で5分間熱圧着し、PENフィルム補強高分子電解質膜を得た。
得られた補強高分子電解質膜の接着強度は、高分子電解質膜とフッ素樹脂コートポリマーフィルムとの間の剥離強度を、JIS K 6854−2:1999に従い測定することにより評価した。剥離強度は、同様に製作した幅25mm、長さ200mmの試験片を用い、引張試験機(島津製作所社製AG−1)において、剥離速度100mm/分で測定した。
補強高分子電解質膜の使用耐久性は、プレッシャークッカー(ヤマト科学社製SP510)において120℃の飽和水蒸気中に試験片を100時間放置した後、上記と同様に剥離強度を測定することにより評価した。
