    摘要： A fluid distribution insert adapted to be received within an inlet header of a fuel cell assembly. 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. An outlet is formed intermediate the first end and the second end. The outlet is adapted to deliver the reactant gas to a plurality of fuel cells of the fuel cell assembly, wherein the hollow insert delivers the reactant gas to the fuel cells in a substantially simultaneous and uniform manner.

    摘要： A fuel cell system is provided having a fuel cell stack including a plurality of fuel cells. The fuel cell system includes an anode supply manifold in fluid communication with the plurality of fuel cells, the anode supply manifold adapted to deliver a anode supply stream to the plurality of fuel cells; an anode exhaust manifold in fluid communication with the anodes of the plurality of fuel cells, the anode exhaust manifold adapted to receive an anode exhaust stream from the plurality of fuel cells; a first valve in fluid communication with the anode supply manifold; and a second valve in fluid communication with the anode exhaust manifold. A method of starting the fuel cell system is also provided. The fuel cell system and method militates against a non-uniform distribution of the anode supply stream to the anodes of the plurality of fuel cells.

    摘要： A bipolar plate for a PEM fuel cell is disclosed. The plate includes a plurality of channels, wherein the ends of the channels are staggered. The plate also includes a plurality of tunnels, wherein the ends of the tunnels are staggered. The plate further includes a cathode and an anode, wherein a portion of the cathode overhangs a portion of the anode. These staggered/offset features allow for an increase the capillary meniscus of water droplets passing therethrough, allowing for a reduction in the pressure required to move the water through the cell and out to the header volume of the stack.
