  • PEM fuel cell stack hydrogen distribution insert
    Patent number: 8679696
    Abstract: A fluid distribution insert adapted to be received within an inlet header of a fuel cell assembly is disclosed. The fluid distribution insert includes a hollow insert with a first end and a second end. An inlet is formed at the first end of the hollow insert in fluid communication with a source of a reactant gas and adapted to receive the reactant gas therein. A plurality of outlets is formed intermediate the first end and the second end. A plurality of flow channels is formed in the hollow insert providing fluid communication between the inlet and the outlets to deliver the fluid to a plurality of fuel cells of the fuel cell assembly, wherein a total flow volume and flow resistance of each of the flow channels is substantially the same to provide for a substantially simultaneous delivery of the reactant gas to the fuel cells.
    Type: Grant
