摘要： 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 wedge section having a first end and a second end. The wedge section forms a fluid flow path between a surface forming the inlet header and the wedge section, wherein the fluid flow path receives a fluid therein and delivers the fluid to a plurality of fuel cells of the fuel cell assembly. The wedge section minimizes a cross-sectional area of the fluid flow path adjacent the second end of the wedge section to maintain a substantially constant fluid velocity along a length of the inlet header.

摘要： A method for filling a fuel cell anode supply manifold with hydrogen prior to a start-up operation to facilitate a substantially even hydrogen distribution across the fuel cell is disclosed. The anode supply manifold is in fluid communication with a source of hydrogen. A first valve in fluid communication with the anode supply manifold and a second valve in fluid communication with an anode exhaust manifold are initially in a closed position while hydrogen is supplied to the anode inlet conduit to pressurize the fuel cell stack. The first valve is then opened to purge at least a portion of a fluid from the anode supply manifold to facilitate a filling of the manifold with hydrogen.
