Abstract:
A fuel cell stack utilizes flow shifting of the anode reactant within the individual fuel cells of the fuel cell stack. The anode side of the fuel cells are separated into two or more flow fields. Anode reactant is supplied in varying quantities to the two flow fields so that anode reactant flowing through one of the flow fields is allowed to back flow into the other flow field and vice versa. The back flowing of anode reactant between the flow fields distributes nitrogen more evenly between the multiple flow fields in each of the fuel cells.
