Disclosed is a process for the manufacture of a catalyst-coated membrane-seal assembly, including: (i) providing a carrier material; (ii-i) forming a first layer, the 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, the 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 including 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.
