FLOW FIELD PLATE WITH RELIEF DUCTS FOR FUEL CELL STACK |
摘要 |
Flow field plate constructions for bipolar plates are disclosed for use in fuel cell stacks that are subject to freezing temperatures. In designs having internal coolant flow fields and reactant backfeed ports, relief ducts are provided in the supporting walls surrounding the backfeed ports in order to allow for ice formation and thus prevent cracking of the plates.
