FUEL CELL STACK AND FUEL CELL MODULE

摘要

A fuel cell stack (10) includes at least one fuel cell unit (20) and a numbe r of interconnects (22) defining at least two openings (24) and including at leas t one flow field (34) for flowing a reagent. Each opening defines a respective fuel manifold (25), including at least one each of intake and exhaust fuel manifolds (251, 252). The fuel cell unit includes an anode (26), a cathode (28), and an electrolyte (27) disposed therebetween. The anode is adjacent to and in both electrical connection and fluid communication with one of the interconnects, which has a flow field (34) tha t guides a fuel flow between the intake and exhaust fuel manifolds. The cathode is adjacent to and in both electrical connection and fluid communication with another interconnect with a flow field (34) that guides an oxidant flow. The fuel cell stack includes a perimeter isolation seal (44) and at least two interior isolation seals (45) for sealing the electrolyte to the respective interconnects.
