Patent ID: 8480838

Claim:
A method of making a membrane electrode assembly comprising the steps of: a) providing a web of polymer electrolyte membrane material; b) providing a laminating station wherein said web of polymer electrolyte membrane material is drawn between a pair of laminating rollers which form a laminating nip; c) die-cutting a first web of first catalyst decal material, said web comprising a removable liner layer and a first catalyst layer, to make a first catalyst decal; d) die-cutting a second web of second catalyst decal material, said web comprising a removable liner layer and a second catalyst layer, to make a second catalyst decal; e) transporting said first catalyst decal to said laminating station; f) transporting said second catalyst decal to said laminating station; g) feeding said first catalyst decal into said laminating nip adjacent to said web of polymer electrolyte membrane material; h) feeding said second catalyst decal into said laminating nip adjacent to said web of polymer electrolyte membrane material concurrently with said first catalyst decal; i) laminating said first catalyst decal, said web of polymer electrolyte membrane material and said second catalyst decal to form a laminate.
