Fuel cell system configurations

Patent · Thu Jan 01 00:00:00 EST 1981

OSTI ID:863923

Kothmann, Richard E.; Cyphers, Joseph A.

Fuel cell stack configurations having elongated polygonal cross-sectional shapes and gaskets at the peripheral faces to which flow manifolds are sealingly affixed. Process channels convey a fuel and an oxidant through longer channels, and a cooling fluid is conveyed through relatively shorter cooling passages. The polygonal structure preferably includes at least two right angles, and the faces of the stack are arranged in opposite parallel pairs.
