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 system and method for reducing the corrosive effects of an air/hydrogen front in a fuel cell stack. The method includes shutting down the fuel cell stack and then initiating a hydrogen sustaining process where hydrogen is periodically injected into an anode side of the fuel cell stack while the stack is shut down for a predetermined period of time. The method determines that the hydrogen sustaining process has ended, and then purges the anode side and a cathode side of the fuel cell stack with air after the hydrogen sustaining process has ended and the stack is still shut-down.
