Abstract
A fuel cell interconnect includes fuel ribs disposed on a first side of the interconnect and a least partially defining fuel channels, and air ribs disposed on an opposing second side of the interconnect and at least partially defining air channels. The fuel channels include central fuel channels disposed in a central fuel field and peripheral fuel channels disposed in peripheral fuel fields disposed on opposing sides of the central fuel field. The air channels include central air channels disposed in a central air field and peripheral air channels disposed in peripheral air fields disposed on opposing sides of the central air field. At least one of the central fuel channels or the central air channels has at least one of a different cross-sectional area or length than at least one of the respective peripheral fuel channels or the respective peripheral air channels.
