Abstract:
A method of manufacturing a fuel cell membrane electrode assembly comprising forming and compressing a stack having a plurality of layers in a desired orientation. The layers comprise a membrane, a cathode, an anode, and at least one edge protection layer. The method includes providing at least one mechanical reinforcing layer adjacent the anode or cathode layer, and allowing the electrodes to relax under high heat to remove stress prior to lamination.
