Abstract
A method for assembling a fuel cell humidifier can include steps of providing a first humidifier plate and a humidifier membrane. The first humidifier plate can have a first top plate surface. The humidifier membrane can have a bottom membrane surface. The bottom membrane surface of the humidifier membrane can be disposed on the first top plate surface of the first humidifier plate. The first humidifier plate can be partially melted. This can permit the first top plate surface of the first humidifier plate to permeate into the bottom membrane surface of the humidifier membrane. The first humidifier plate can be cooled, which can fuse the first top plate surface of the first humidifier plate with the bottom membrane surface of the humidifier membrane.
Claims5
A method for assembling a fuel cell humidifier, the method comprising:
- providing a first humidifier plate with a first top plate surface and a first recess perimeter, and a second humidifier plate with a second top plate surface and a second recess perimeter;
- providing a humidifier membrane with a bottom membrane surface;
- disposing the bottom membrane surface of the humidifier membrane on the first top plate surface of the first humidifier plate;
- disposing the second top plate surface of the second humidifier plate on a top membrane surface of the humidifier membrane;
- partially melting the first humidifier plate, thereby permitting the first top plate surface of the first humidifier plate to permeate into the bottom membrane surface of the humidifier membrane;
- partially melting the second humidifier plate, thereby permitting the top membrane surface of the humidifier membrane to permeate into the second top plate surface of the second humidifier plate and the second recess perimeter of the second humidifier plate to contact the first recess perimeter of the first humidifier plate;
- and
- cooling the first humidifier plate, thereby fusing the first top plate surface of the first humidifier plate with the bottom membrane surface of the humidifier membrane.
A method for assembling a fuel cell humidifier, the method comprising:
- providing a plurality of humidifier plates;
- providing a plurality of humidifier membranes;
- disposing each of the humidifier membranes between a respective pair of two of the humidifier plates to form a plurality humidifier units;
- stacking each of the humidifier units together to form a humidifier stack;
- partially melting each of the humidifier plates of the humidifier units in the humidifier stack, thereby permitting respective plate surfaces of the humidifier plates to permeate into respective membrane surfaces of the humidifier membranes and respective recess perimeters of the humidifier plates to contact each other;
- and
- cooling each of the humidifier plates, thereby fusing the respective plate surfaces of the humidifier plates with the respective membrane surfaces of the humidifier membranes and fusing the respective recess perimeters of the humidifier plates to form a seal about each of the humidifier membranes.
