Summary: | To provide a roll of a composite polyelectrolyte membrane with suppressed swelling at the edges in the width direction.SOLUTION: A roll of a composite polyelectrolyte membrane includes a first layer including a polymer electrolyte, a second layer including a porous base material, and a third layer including a polymer electrolyte on a long strip-shaped base film in this order, and the widthwise length (W3) of the third layer is smaller than the widthwise length (W2) of the second layer.SELECTED DRAWING: Figure 1
【課題】幅方向端部の盛り上がりが抑制された、複合化高分子電解質膜のロール状物を提供する。【解決手段】長尺帯状の基材フィルム上に、高分子電解質を含む第1の層、多孔質基材を含む第2の層、高分子電解質を含む第3の層をこの順に有する複合化高分子電解質膜のロール状物であって、該第3の層の幅方向長さ(W3)が該第2の層の幅方向長さ(W2)より小さいことを特徴とする、複合化高分子電解質膜のロール状物。【選択図】図1 |
