  • Patent number: 9997792
    Abstract: An electrical connection system for cell voltage monitoring in a fuel cell stack. The fuel cell stack comprises a plurality of layers and a plurality of electrically conductive connection tabs extending outwardly from at least one face of the stack. The electrically conductive connection tabs are each formed as a laterally extending free portion of a flexible sealing gasket. Other portions of the gasket are disposed to provide sealing engagement between at least two layers of the fuel cell stack. By using the gasket material to form such electrical connection tabs, rather than flow plates, the connection tabs are made flexible to make it easier to connect to standard arrays of connectors in connector assemblies.
    Type: Grant
