摘要： Electrical contact surfaces of a bipolar plate for a fuel cell assembly are formed of metals or metal alloys which when oxidized form highly conductive oxide passivation layers, thus maintaining high electrical conductivity and continuity through the fuel cell and forestalling corrosion failure of a cell assembly. Alloy composition systems such as, but not limited to, Ti—Nb, Ti—Ta, La—Sr—Cr, and La—Sr—Co are known to form oxide passivation layers which are highly conductive. The passivation layers may be formed in situ after assembly of a fuel cell or may be provided in an oxidative step during manufacture. The bipolar plate may be formed entirely of one or more of such alloys or may be formed of an inexpensive substrate metal having the alloy layers coated thereupon.

摘要： A composite structure with tailored anisotropic energy flow is described. The structure consists of an array of two-dimensional electrodes with anisotropic geometrical shapes on a semiconductor or semimetal layer that in turn is on a metal baselayer. An applied voltage between the two-dimensional electrode array and the baselayer renders the regions under the electrodes insulating such that the anisotropic regions interact with energy flow in the semiconductor or semimetal layer. Depending on the orientation of the anisotropic insulating regions with respect to the principal direction of energy flow, the energy flow in the semiconductor or semimetal layer is greater in a principal direction and is lower in an opposite direction.
