Abstract
A fuel cell stack includes flow plates that are arranged to communicate reactants through the fuel cell stack. The flow plates include an anode cooler plate that is substantially identical to a cathode cooler plate of the flow plates.
Claims29
A fuel cell stack comprising:
- flow plates arranged to communicate reactants through the fuel cell stack, the flow plates including an anode cooler plate that is substantially identical to a cathode cooler plate of the flow plates.
A fuel cell flow plate having a design to function as an anode cooler plate in a first orientation in a fuel cell stack and function as a cathode cooler plate in a second orientation in the fuel cell stack, the second orientation being rotated approximately one hundred eighty degrees from the first orientation.
A method for forming a fuel cell stack, comprising:
- arranging flow plates to communicate reactants through the fuel cell stack;
- using one of the plates to form an anode cooler plate of the fuel cell stack;
- and
- using another one of the plates to form a cathode cooler plate of the fuel cell stack, the cathode cooler plate being substantially identical to the anode cooler plate.
