Manifold dielectric barrier for a fuel cell electrical power generation system

摘要

A manifold dielectric barrier for use in a power section of a fuel cell electrical power generation system. The power section comprises a fuel cell stack and two external reactant manifolds for respectively conveying oxygen-rich gas and fuel into the fuel cell stack. The power section also includes discharge manifolds for conveying spent products away from the fuel cell stack. The manifold dielectric barrier dielectrically isolates the fuel cell stack from each of the manifolds. The manifold dielectric barrier includes an impermeable ceramic member, a first ceramic gasket intermediate of and contiguous with the ceramic member and the fuel cell stack, and a second ceramic gasket intermediate of and contiguous with the ceramic member and each of the manifolds.
