    • A process for the manufacture of a catalyst-coated membrane-seal assembly, said process comprising the steps of: (i) providing a carrier material; (ii-i) forming a first layer, said first layer being formed by: (a) depositing a first catalyst component onto the carrier material such that the first catalyst component is deposited in discrete regions; (b) drying the first layer; (ii-ii) forming a second layer, said second layer being formed by: (a) depositing a first seal component, such that the first seal component provides a picture frame pattern having a continuous region and void regions, the continuous region comprising second seal component and the void regions being free from second seal component; (b) depositing a first ionomer component onto the first layer, such that the first ionomer component is deposited in discrete regions; and (c) drying the second layer; wherein the void regions of the first seal component are centrally positioned over the discrete regions of the first ionomer component; wherein the discrete regions of the first ionomer component are centrally positioned over the discrete regions of the first catalyst component; and wherein steps (ii-ii)(a) and (ii-ii)(b) are carried out in either order; (iii) removing the carrier material.; is disclosed.
    • 一种用于制造催化剂涂覆的膜 - 密封组件的方法,所述方法包括以下步骤:(i)提供载体材料; (ii-i)形成第一层,所述第一层通过以下步骤形成:(a)将第一催化剂组分沉积到所述载体材料上,使得所述第一催化剂组分沉积在离散区域中; (b)干燥第一层; (ii-ii)形成第二层,所述第二层通过以下步骤形成:(a)沉积第一密封部件,使得所述第一密封部件提供具有连续区域和空隙区域的相框图案,所述连续区域包括第二层 密封部件和空隙区域没有第二密封部件; (b)将第一离聚物组分沉积到第一层上,使得第一离聚物组分沉积在离散区域中; 和(c)干燥第二层; 其中所述第一密封部件的空隙区域位于所述第一离聚物部件的离散区域上方中心定位; 其中所述第一离聚物组分的离散区域居中定位在所述第一催化剂组分的离散区域上方; 并且其中步骤(ii-ii)(a)和(ii-ii)(b)以任何顺序进行; (iii)除去载体材料; 被披露。
