Abstract
A method for producing bipolar plates includes removing scrap material from an electrically conductive plate. The scrap material is created when the plate is cut through to produce a fluid flow opening therein and in which an inlet manifold opening and an outlet manifold opening are located at the ends of the fluid flow opening and in communication therewith.
Claims5
A method of producing a fuel cell stack, the method comprising:
- a) providing a Membrane Electrode Assembly (MEA) having an anode, a cathode and an electrolyte located therebetween;
- b) locating a n oxidant flow field plate against the cathode;
- c) locating a fuel flow field plate against the anode;
- d) locating a separator plate against the oxidant flow field plate;
- and
- e) compressing the plates to produce the fuel cell stack, each of the plates each having been cut through to create a plurality of openings therein and finished, the plates being made from an electrically conductive material.
