An elastomeric cell frame for a fuel cell includes an insert which includes: a membrane electrode assembly including a polymer electrolyte membrane and a pair of electrode layers respectively disposed on opposite sides of the polymer electrolyte membrane; and a pair of gas diffusion layers disposed and bonded on upper and lower surfaces of the membrane electrode assembly, respectively. The insert further includes an elastomeric frame disposed in an external region of the insert. The elastomeric frame surrounds one of opposite edge surfaces of the insert and a side surface of the insert, the elastomeric frame being interface-bonded, through thermal bonding, to portions of the polymer electrolyte membrane and the electrode layers exposed at the one of opposite edge surfaces of the insert and the side surface of the insert.

Systems for creating electrodes for polymer electrolyte membrane fuel cells include an XY stage having a heated vacuum table physically coupled to the XY stage. The vacuum table has a working face with a plurality of channels formed therein to communicate vacuum pressure from a port coupled to a vacuum source to the channels. A sheet of perforated heat-conductive material has staggered holes configured to evenly distribute the vacuum pressure from the channels through the perforated sheet. A heat-conductive wire mesh is placed over the perforated sheet, and has openings smaller than the staggered holes such that a membrane material placed on the wire mesh is not deformed by the vacuum pressure. A nanopipette or micropipette coupled to a pump is configured to deposit electrode ink onto an exposed surface of the membrane material as the controller device causes the XY stage to move the vacuum table to control deposition of the electrode ink onto the surface of the membrane material.
