DescriptionSolid-oxide fuel cell electrode: a molded ceramic rod (probably zirconium oxide and calcium oxide), the lower portion of which is undercut to form a ribbed, segmented profile, with electrical pickup wires attached at various points. The rod is attached to a machined brass mounting flange at the top, with knurled (valve?) knobs, gas (hydrogen) connector, and eight electrical terminals, each having a short pigtail of wire, with paper numerical identification labels. In operation, the unit would have fit into a containment housing (not included); there is a plastic storage tube on the rod, which is not related to this objectDimensions3.5 x 2.1 in. (8.9 x 5.3 cm)
Historical NotesResearchers at Westinghouse developed the zirconium oxide / calcium oxide fuel cell in 1962; the hard ceramic rod acts as an electrolyte (solid, rather than liquid) when heated to approximately 1,000 degrees Fahrenheit; a crystal lattice is formed within the material, and a fuel gas (hydrogen) is passed over the unit; electricity generated is collected via the attached wires. Note that this unit was a laboratory / research prototype.
