摘要： A process for manufacturing a reinforced membrane-seal assembly includes: (i) providing a carrier material; (ii) providing a planar reinforcing component having one or more first regions including pores and a second region including pores, the first regions being patches and non-continuous and the second region surrounding the first regions and being continuous; (iii) depositing an ion-conducting component; (iv) drying the ion-conducting component; (v) depositing a seal component; (vi) drying the seal component (vii) removing the carrier material. In embodiments, ion-conducting component fills the pores in the first regions and seal component fills the pores in the second region; steps (ii), (iii) and (v) can be carried out in any order; step (iv) is carried out subsequent to step (iii); step (vi) is carried out subsequent to step (v); and steps (iv) and (vi) are carried out subsequent to step (ii). Also disclosed is an assembly prepared by such process.
